  • Optical rotation sensor as well as method of manufacturing an optical rotation sensor
    Patent number: 9863771
    Abstract: An optical rotation sensor is provided, comprising an optical ring resonator (RR) formed by a one-dimensional photonic crystal (1D PhC) waveguide, and a bus waveguide. A light input section of the bus waveguide is connectable to a light source, and a light output section of the bus waveguide is connectable to a light detector. The bus waveguide is optically coupled to the ring resonator within a coupling area which is located between the light input section and the light output section of the bus waveguide. The optical rotation sensor is configured to measure a shift of frequency of a resonance area (or a plurality of resonance areas) close to a band edge of a photonic band gap of the ring resonator, wherein the shift of frequency is caused by a rotation of the optical rotation sensor.
