Switchable Optical Phased Prism Arrays For Beam Steering

摘要

The Wollaston prism with large deflection angle usually has small cross section size, which constrains its application in beam steering. This paper investigates the possibility of assembling the prisms together to increase the cross section size. Single-layer- and double-layer- assembled Wollaston prisms are investigated. The compression ratio and transmission ratio associated with the diffraction efficiency of assembled prisms are calculated and formulated.
