单模多模宽带转换器

THz宽带相位变换器众所周知，宽带相位变换器的计算方法在一般情况下不适用于高分辨率的测量系统，我们的仪器充分考虑到了干涉效应。 l 带相位变换器中包括特殊的定向石英镜片。l 这些镜片组合在一起并固定在支架上，构成太赫兹宽带相位变换器，可等效为两个部件“retarder” 和“rotator”： retarder提供相移，rotator能够在偏振面内转动ω的角度。l 太赫兹宽带相位变换器依赖于ω值存在两种类型： 1）ω值不为零，它取决波长，我们称为：消色差偏振转换器。 2）ω值大约为零，在相应的波长范围内为常数，我们称为：消色差波片。 主要参数：类型THz Achromatic Polarization Converter太赫兹消色差偏振转换器THz Achromatic Wave Plate太赫兹消色差波片延迟L/4L/4操作波长范围60-300 um ，或用户指定60-95 um ，或用户指定椭圆率公差+/- 3%，或用户指定+/- 10 %，或用户指定通光孔径,25 mm (标准) ，或25mm (用户指定)支架传统光学底座或旋转器

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.
