论文摘要
我们介绍了N型INSB中法拉第效应的测量。 VERDET系数在$ 10^{17} $ $ \ text {cm}^{ - 3} $的$ 10^{17} $ = 8 $ = 8 $μ$ m-12 $ $ m $ m $ m $ m长波红外线制度中的一系列载体浓度确定。测量吸收系数，并为每个样品计算出功绩图。从这些测量值中，我们计算了载体有效质量，并说明了波长的优点图的变化。讨论了一种通过法拉第旋转创建可调的带通滤波器的方法，以及原型设备的初步结果。
We present measurements of the Faraday effect in n-type InSb. The Verdet coefficient was determined for a range of carrier concentrations near $10^{17}$ $\text{cm}^{-3}$ in the $λ$ = 8 $μ$m - 12 $μ$m long-wave infrared regime. The absorption coefficient was measured and a figure of merit calculated for each sample. From these measurements, we calculated the carrier effective mass and illustrate the variation of the figure of merit with wavelength. A method for creating a tunable bandpass filter via the Faraday rotation is discussed along with preliminary results from a prototype device.
