Tydex生产的衍射光栅用于太赫兹频率范围的光谱测量。它们是凸面相位传输光栅。这种光栅的规则结构是通过在透明衬底上切割平行的破折号(凹槽)来实现的。衬底由太赫兹范围内透明的材料制成，如TPX(聚甲基戊烯)和ZEONEX(环烯烃聚合物)。光栅可用于:• 太赫兹光谱 • 太赫兹诊断仪器 • 光电设备 • 天文学和天体物理应用，包括天基 • 材料研究。光栅在0.3-3太赫兹范围内的以下传输频段有四个标准选项:0.28-0.55太赫兹 0.49 - -0.98太赫兹 0.87 - -1.75太赫兹 1.56 - -3.12太赫兹。其他频段0.3-3太赫兹范围内的光栅可根据客户要求生产。TPX和ZEONEX板在切割槽前的两侧抛光后的透射光谱如下图所示。 太赫兹光栅通常做成方形，一面35毫米到70毫米。其他形状和尺寸可根据需要提供。根据预期的应用，衍射光栅可以用于各种光学安排，有或没有聚光透镜。用夫琅禾费近似法计算了单色波的光栅参数、衍射波强度和一阶最大角。为了验证操作，并比较计算和实际参数，测量了光栅在不同太赫兹辐射源下的各种光学排列方式下的特性。使用了两个光源。第一种是远红外激光，这是一种亚毫米的甲醇蒸汽激光，由可调谐的CO2激光（Peter the Great St. Petersburg Polytechnic University）泵浦。第二个是自由电子激光器(FEL)，一种自由电子激光器(Siberian Synchrotron and THz Radiation Center, Budker Institute of Nuclear Physics, RAS)。图3和图4描绘了使用FIR激光器作为辐射源时，间距d=250 μm的TPX和ZEONEX光栅的单色波强度(λ=118 μm)与衍射角的关系。图5和图6给出了单色波的强度(λ=141 μm)对衍射角的影响。在第二种情况下，一个会聚透镜被放置在光栅和辐射传感器之间。这些图的比较表明，在第一种情况下，零阶和一阶极大值比透镜排列更宽。这是由会聚透镜使平行光束聚焦的结果。用户在根据自己的意图设计实验时，必须考虑到这一点。当光栅用于研究辐射源的特性(功率、光束形状、能量分布等)时，透镜是多余的。但当光谱线需要分辨时，透镜就变得必不可少。对于使用瑞利准则确定特定透射带的衍射光栅，衍射单色波的强度与波长有关。它在山脉中部达到最大值，在边界附近下降。例如,数据3-6结果表明，对于间距为250 μm的TPX和ZEONEX衍射光栅(透射波段为1.56 ~ 3.12 THz或96 ~ 192 μm)， λ=141 μm单色波的一阶最大光强是λ=118 μm单色波的几倍。(第一个在传输带的中间，而第二个更接近边缘。)它与用夫琅和费近似计算的单色波理论衍射波强度和一阶最大角相匹配。由于测试光栅时使用的辐射源和光学安排不同，下面的强度以任意单位给出。研究数据表明，该方法具有较高的光学效率和运算最大值的分辨率。因此，这种光栅可以有效地用于研究辐射源的光谱，包括低功率源，这是研究太赫兹频率范围的一个重要能力。

Sometimes it' s necessary to have nearly constant retardation at the specified wavelength range. For that case we have developed THz broad-band phase transformers. Basic methods of broad-band phase transformers calculation are well-known. However, they are not suitable for the case if measuring system has high resolution. So we have modified the methods to take into account interference effect. Broad-band phase transformers consist of several specially oriented crystal quartz plates. The plates are stacked together and fixed into a holder. According to Jones formalism system of several retardation plates is optically equal to system containing only two elements: so called &ldquo retarder&rdquo and&ldquo rotator&rdquo (please see Fig.1). Retarder provides required phase shift (usually &pi or &pi /2). Rotator turns the polarization plane at angle &omega .Fig.1. Broad-band phase transformer in terms of Jones formalismand its position relative to polarizer and analyzer. There are two types of broad-band phase transformers: 1) &omega is not 0º and it depends on the wavelength. We call it &ldquo achromatic polarization converter&rdquo (APC). Example of &omega behavior is below. Fig.2.a) Angle &omega of the APC L/4@60-300 um. 2) &omega is about 0º and it is constant within the operating wavelength range. In this case it is usual &ldquo achromatic waveplate&rdquo (AWP) and its operating principle is the same as of monochromatic waveplate.

The variable wheel attenuator consists of 5 wheels. Four wheels contain metalized wedged silicon wafers with different attenuation levels and one wheel is empty. If necessary the empty wheel can be filled with a custom element (e.g. filter). Four attenuators have transmission 30%, 10%, 3%, and 1%. These attenuator elements can be used as a single attenuator or in combination that allows achieving different levels of attenuation. Transmission curves (noise is smoothed) of attenuator elements are shown below. Measurements were made up to 1000 &mu m. However, operating wavelength range is much wider. It follows from physical mechanism of attenuator operation.Fig. Transmission of THz attenuator elements Transmission values of different combinations of attenuators are given in the table below.Common specification: The following THz attenuators are available from stock: Please check our Optics stock.

The key instrument in polarimetry is polarization modulator which identifies and measures polarized signal. Plano-plano plates, made of birefringent material, are used for modifying polarization state of radiation. A waveplate works by shifting the phase between two perpendicular polarization components of the wave. The most common types of waveplates are a half-wave plate (&lambda /2 plate) and a quarter-wave plate (&lambda /4 plate). &lambda /2 plate gives phase delay &pi and &lambda /4 plate - &pi /2. A half-wave plate changes the polarization direction of linear polarized light. A quarter-wave plate changes linearly polarized light to circular and vice versa.Waveplate will not change the polarization of linearly polarized beam if the polarization direction is along one of waveplate axes.

太赫兹光电导天线太赫兹天线THz antennas PCA产品简介 光电导天线是目前THz时域光谱仪中常用的THz产生与探测器件，生产工艺已经趋于成熟。上世纪 80 年代，太赫兹之父 D．Grischkowsky 等人利用光电导天线产生了 THz 辐射。这种方法发展到现在，已经成为一种较为普遍的实验方法。如下图，偶极天线结构被制作在低温生长的GaAs 上，利用光子能量大于 GaAs 禁带宽度的超短脉冲激发天线装置，是半导体内部产生电子-空穴对，这些载流子再外加电场的作用下将会加速运动形成一个瞬态电流，从而辐射出 THz 脉冲。Batop公司简介 BATOP GmbH成立于2003年，是一家曾隶属于德国耶拿大学的私人创新型公司。BATOP从事的专业领域包括：低温分子束外延技术，介质溅射镀膜，晶圆加工和芯片安装技术。Batop的一个主要的产品系列是用于太赫兹发射和探测的太赫兹光电导天线(PCA)。BATOP不仅提供单带隙天线，还包括整合了微透镜的高能大狭缝交叉天线阵列和整套的太赫兹时域光谱仪。 太赫兹光电导天线的激发波长为800nm到1550nm之间。BATOP借助强大的研发能力来不断提高自己的产品， 我们始终和客户在一起，很好的满足他们的需求。 光电导天线选型推荐天线类型 发射探测低频段高频段低激发光强高激发光强蝴碟形天线++ ++ +--+平行形天线+ ++-+ ++-领结形天线++ +++ +-天线阵列+ ++ + -+ +-+ +领结指间形天线 +++++ +-螺旋形天线+ ++ ++ +-+-PCA 产品列表激发光波长 530 nm ... 860 nm激发光波长 800 nm ... 1100 nm激发光波长 1000 nm ... 1550 nm光导天线封装形式以及相关附件：

However, reflection losses can be reduced by THz AR coating. We offer polyethylene and parylene coatings. We have developed polyethylene coating technology for plane surface. Polyethylene coatings are applied for windows only. The coated windows are mounted for easy handling. Parylene coating technology for plane surfaces is well known in microelectronics. We have improved it to achieve coating on optical surfaces (plane as well as spherical ones). So parylene coatings are used for windows as well as for lenses. AR coating wavelength range is specified by customer. It' s possible to make AR coatings for ranges within the wide interval from 60 &mu m to 1300 &mu m. The following AR coatings are offered:1. Two-sided AR coating It is used for windows and meniscus lenses. Currently AR coatings centered at the following ranges are developed: - polyethylene coatings - 60-80 &mu m, 110-160 &mu m, 160-220 &mu m, 320-430 &mu m, 375-510 &mu m, 480-650 & mu m, 535-725 &mu m, 645-870 &mu m, 695-940 &mu m, and 965-1305 &mu m - parylene coating 99-125 &mu m. HRFZ-Si can be coated by polyethylene as well as by parylene while crystal quartz - by parylene only. Due to AR coating transmittance is &ge 90% within any range mentioned above. Examples of transmission curves of polyethylene coated and uncoated HRFZ-Si windows as well as parylene coated and uncoated crystal quartz windows are shown below. Fig. 1. Transmission of uncoated and two-sided polyethylene coated HRFZ-Si windows. AR coating is centered at 160-220 &mu m.Fig. 2. Transmission of uncoated and two-sided parylene coated crystal quartz windows. AR coating is centered at 99-125 &mu m.2. One-sided AR coating Usually it is applied for hemispherical lenses. Plane lens surface is not coated since the lens is used as photoconductive antenna in THz TDS setup or in superconductive bolometer. Currently AR coating centered at the range of 99 um to 125 um is developed for some specific applications. AR coating increases transmittance of the hemispherical lens by 30 %. Since it' s enough difficult to measure transmission of hemispherical lens due to its shape we have simulated transmission curves of AR coated and uncoated lenses (please see them below). Fig.3. Simulated transmission of uncoated and one-sided (spherical surface) parylene coated hemispherical lenses. AR coating is centered at 99-125 &mu m. Experimental results achieved by one of our customers confirmed increasing of transmission due to AR coating. The gain in power in his instruments while using one-side coated hyper-hemispherical lens was about 30-50% at 111 um. As you see transmittance of uncoated HRFZ-Si hemispherical lens is 6 % only. It is connected with the effect of total internal reflection. The angle of total internal reflection is about 17 deg. Due to high refractive index of silicon and lens geometry major part of penetrated into the lens THz radiation is reflected from plane lens surface-air interface. Therefore clear aperture of the hemispherical lens is 40% only. Polyethylene AR coatings as well as parylene ones centered at wavelength ranges differing from mentioned above are in progress.筱晓（上海）光子技术有限公司Micro photons (Shanghai)Technology Co., LTDEmail：info@microphotons.com上海总部:电话：021－64149583地址：上海市闵行区春都路358弄27号楼504，201108

By using the microlens array only every second gap between the finger structure is excited by the laser. The fill factor of the lens array of 73.5 % ensures, that nearly the total optical laser energy is used for excitation of carriers. Despite of the large emitting area the needed voltage for the carrier excitation is low ( 35 V) because of the small gap of only 5 μm. The coherent excitation of the single emitters located at every microlens spot results in a constructive interference of the radiated THz waves in the far field.Mounting:iPCA chip, size 4 mm x 4 mm, thickness 625μm, mounted on 25.4 mm diameter black aluminium mount with prealigned hyperhemispherical silicon lens ? 12 mm and prealigned fused silica lens array, size 2 mm x 2 mm, and 1 m coaxial cable (RG 178) with BNC or SMA connector.

太赫兹单色波片一般应用于转换特定波长的偏振态。由于这些波片只能应用于单一波长，在某些情况下（如可调谐太赫兹源）使用起来会很不方便。这种情况下，可调谐太赫兹波片（TWPC）则是一个合理的选择。上海屹持光电最新推出的可调谐太赫兹波片可以在一段光谱范围内实现任意单一波长的相位转变，配套的软件可以计算转换参数和范围。可调谐太赫兹波片由三块透明的石英双折射片子组成，每个片子都安装在一个转盘上可以360°旋转。三个转盘则严格对准固定在同一个基板上。这些片子可以被旋转到特定角度以满足特定波长不同偏振态的相位延迟。旋转角度则可以根据软件计算，除了片子的旋转角度，软件还可以计算相位延迟量，有效光轴以及偏振角度和对应波长的关系。可调谐太赫兹波片（TWPC）参数：工作模式操作波长范围半波片80um-160um（1.875-3.75THz）内任意波长1/4波片150um-300um（1-2THz）内任意波长双折射滤波片120um（2.5THz）通光孔径24mm测试数据可调太赫兹谐波片（TWPC）的不同工作模式测试数据均在傅里叶光谱仪 Bruker Vertex 70中完成1，可调太赫兹谐波片（TWPC）作为1/2波片TWPC放置在两块平行的偏振片之间，测试波长120um2，可调太赫兹谐波片（TWPC）作为1/4波片计算数据：TWPC放置在两块偏振片之间，检测偏振片在不同角度下的透过率曲线，测试波长220um实测数据：TWPC放置在两块偏振片之间，检测偏振片在不同角度下的透过率曲线，测试波长220um3， 可调太赫兹谐波片（TWPC）作为双折射滤波片TWPC放置在两块正交的偏振片之间，测试波长120um

产品简介 太赫兹隔离器是一个具有单向通过性的非交互性器件。我们研发出的宽带太赫兹隔离器是基于磁光介质，无需外部磁场。 太赫兹隔离器包含两个特定方向偏振的太赫兹偏振片和一个磁光介质，磁光介质会将入射的宽谱太赫兹光束的偏振态旋转45°。太赫兹隔离器的运行机制为：太赫兹光束经过第一个偏振片变成线性偏振的光束，然后通过磁化的 钡铝六角铁氧体，由于法拉第效应，太赫兹光束的偏振态会被旋转45°。接下来于太赫兹光束通过第二个偏振片（与第一个偏振片成45°夹角），因此通过磁光介质后的太赫兹偏振方向刚好和第二个偏振片的检偏方向一致；当同样的太赫兹光束被反射回太赫兹隔离器时，其偏振态也会被旋转45°，而和最初入射的第一个偏振片的偏振方向正交而无法出射。以上就是太赫兹隔离器的运行机制。太赫兹隔离器技术参数操作频率范围0.2-1THz透过率不低于20%反射率不高于10%隔离度不低于20dB通光孔径25mm（标准）*尺寸直径60mm长度35mm*其他尺寸可以接受定制太赫兹隔离器透过率参数图1，透过和反射的振幅透过率谱线 图2. 隔离度曲线太赫兹隔离器可以用于保护敏感的太赫兹辐射源不被反射回波损坏。而且太赫兹隔离器也可以减少噪声噪声水平以及通过阻挡回波提供光学隔离度。上海屹持光电技术有限公司地址：上海市闵行区剑川路955号1108室电话：021-62209657 021-54843093 传真：021-54843093邮箱：[email protected] 网站：www.eachwave.comQQ：2920058626 微信：jesse-xue

Sometimes it' s necessary to have nearly constant retardation at the specified wavelength range. For that case we have developed THz broad-band phase transformers. Basic methods of broad-band phase transformers calculation are well-known. However, they are not suitable for the case if measuring system has high resolution. So we have modified the methods to take into account interference effect. Broad-band phase transformers consist of several specially oriented crystal quartz plates. The plates are stacked together and fixed into a holder. According to Jones formalism system of several retardation plates is optically equal to system containing only two elements: so called &ldquo retarder&rdquo and &ldquo rotator&rdquo (please see Fig.1). Retarder provides required phase shift (usually &pi or &pi /2). Rotator turns the polarization plane at angle &omega . Fig.1. Broad-band phase transformer in terms of Jones formalism and its position relative to polarizer and analyzer. There are two types of broad-band phase transformers: 1) &omega is not 0º and it depends on the wavelength. We call it &ldquo achromatic polarization converter&rdquo (APC). Example of &omega behavior is below. Fig.2.a) Angle &omega of the APC L/4@60-300 um. 2) &omega is about 0º and it is constant within the operating wavelength range. In this case it is usual &ldquo achromatic waveplate&rdquo (AWP) and its operating principle is the same as of monochromatic waveplate.
