“…The resonant half-wavelength decrease of polarizing efficiency in transmission is the same effect as observed in dual-layer wire-grid polarizers [27]. Away from these fre- quencies, however, the polarizing efficiency of dual grids is squared (doubled in decibels) as compared to the case of a single grid.…”

We investigated photoconductive gratings in the resonant semiconductor layers as light-controlled polarizers for the millimeter (MM) waves. We compared the effects of strip-like, wire-like, and fin-like gratings excited by the red light and the IR radiation in Silicon wafers, respectively. The fin-like gratings are shown to be the preferred structures that can operate at the limited light intensity. The light-sensitive shift of maxima of transmitted power and polarizing efficiency towards the lower frequency band is observed. The effect makes photoconductive gratings and similar patterns potentially suitable for the design of light-controlled frequency-tuning and frequency-modulating components of resonant quasi-optical devices.

“…In 2007, Yurchenko et al [15] presented free-standing dual-layer wire-grid polarizers for MM wave bands. Experimental testing of these polarizers [16] confirmed a quadratic growth of polarization extinction ratio expressed in relative units as compared to single gratings in the frequency band of 75-110 GHz. Fabrication technology imposed, however, limitations on the performance of gratings in the higher frequency bands, i.e., for THz (sub-MM) waves.…”

Multilayer grid polarizers for millimeter waves produced with photolithographic technology have been simulated. Polarizers have spectral bands of enhanced performance where polarization extinction ratio in decibels grows in proportion to the number of layers. Full-wave modeling is compared with three asymptotic models for subwavelength gratings using adjusted grating parameters. Random variations of interlayer spacings reduce the enhancement of polarizing performance, yet the latter continues to grow in proportion to the number of layers. Broadband signal detection is also considered.
