Abstract
The disclosed structures and methods are directed to a chip for an optical gyroscope and methods of manufacturing the chip for the optical gyroscope. The chip comprises a substrate, a waveguide having a first waveguide cladding layer and a waveguide core; and a ring resonator having a first ring cladding layer and a ring resonator core attached to the first ring cladding layer. A side wall of the ring resonator core forms an obtuse angle with an upper surface of the substrate. The method comprises etching a ring groove and a waveguide groove; placing the optical fiber ring into the ring groove and the optical fiber waveguide into the waveguide groove. The method further comprising splicing two ends of an optical fiber; annealing the ring junction of the optical fiber ring; and attaching the optical fiber waveguide to the waveguide groove and the optical fiber ring into the ring groove.
