Magneto-optical properties of InSb for infrared spectral filtering
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 $\lambda$ = 8 $\mu$m - 12 $\mu$m long-wave infrared regime. The absorption coefficient was measured and a figure of meri...

| description | 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 $\lambda$ = 8 $\mu$m - 12 $\mu$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. |
