Waveguide ring resonator as integrated optics for rotation sensor

摘要

To obtain a micro optic rotation sensor (MORS), a passive ring resonator (PRR) based on channel waveguide was designed and investigated. The waveguide structure of the resonator includes a ring waveguide as well as two directional couplers. The theoretical resolution and transfer functions of the MORS are discussed, and the PRR parameters are determined. According to the sensitivity requirement, the PRR frequency detecting system is discussed, and different detecting schemes are compared.
