摘要：
We present dual-function grating element under total internal reflection (TIR) and second Bragg angle mounting. There are three diffracted orders which are different from most reported Littrow mounting or normal incidence. Grating profile parameters are optimized in order to obtain high efficiency for TE polarization and good uniformity for TM polarization using rigorous coupled wave analysis (RCWA). The fabrication tolerance is investigated, which should be useful guideline for manufacture such a dual-function grating element. The diffractive optical element has novelty of dual-function grating, high efficiency of TIR, and new incidence mounting of second Bragg angle.
