Abstract

In this paper, an integrated optical chip fabricated on the substrate of GaAs for optical fiber gyroscope is completed. The chip is composed of polarizer, beam splitter, phase modulator and single-mode waveguide. The chip is much smaller than that fabricated on LiNbO₃, the size is 25 mm X 0.5 mm. The extinction ratio of the polarizer is designed to be better than 40 dB. Two light spots coming out of the beam splitter has been monitored. The half wave voltage of the phase modulator is below 5 v.
