Residual Intensity Modulation Induced Error in Resonator Fiber Optic Gyroscopes With Reciprocal Detection

open access: yesIEEE Photonics Journal, 2021
In the resonator fiber optic gyroscope (RFOG), both the residual intensity modulation (RIM)-induced error and backscattering-induced noise need to be effectively suppressed. When the clockwise and counterclockwise resonance detection adopt the same phase

Research of Gate-Tunable Phase Modulation Metasurfaces Based on Epsilon-Near-Zero Property of Indium-Tin-Oxide

open access: yesPhotonics, 2022
In this paper, we proposed a reflection phase electrically tunable metasurface composed of an Au/Al2O3/ITO/Au grating structure. This antenna array can achieve a broad phase shift continuously and smoothly from 0° to 320° with a 5.85 V applied voltage ...
