Model of Liquid Crystal on Silicon Device with Sub-Wavelength Grating Structure
Chuan Shen, Sui Wei, Haixiu Yu, and Bo Tao
Herein, a sub-wavelength gold (Au) grating is sputtered onto an indium tin oxide electrode of a classical liquid crystal on silicon (LCoS). After it is mounted on a thin liquid-crystal cell with a bottom aluminum electrode, a composite resonant waveguide structure, namely GLCoS, is created. In contrast to LCoS that ope

Improved Triangular Window Apodization Function Based on Zero-Order Bessel Function
Jinglan Deng, Jingjing Tong, Minguang Gao, Xiangxian Li, Yan Li, Xin Han, and Wenqing Liu
The Fourier transform is commonly used in interferogram analysis. However, owing to the truncation effect, the direct application of Fourier transform for sampled data tends to cause spectral leakage. To address this problem, the apodization function is often adopted. In this paper, we first analyze the performances of
