Abstract

A fiber-optic passive ring-resonator gyro (FOPRG)¹⁾ has an advantage of reducing a fiber length over a conventional fiber-optic interferometric gyro. However, the FOPRG has several peculiar problems to be solved in order to achieve the high sensitive detection of the rotation rate. Among them, reducing the reflection is very important. For example, it was reported that the backscattered light generated in the fiber ring splits the resonant peak into two, resulting in the degradation of the FOPRG linearity.²⁾
