Transmitted Phase Measurement System of A Guided-Mode Resonance Device Based on Interference Fringe Image

This paper reports a phase measurement system of a guided-mode resonance (GMR) device to detect the transmitted phase difference between s- and p-polarization of the incident light under the different incident angles. The GMR device is a resonance grating waveguide and can be used as a sensor to detect the refractive index change on the grating surface. The experimental results of the compact comm...
