Abstract
An optical ring resonator-based gyroscope includes a photonic integrated circuit (PIC) chip including a plurality of optical elements, the plurality of optical elements including a resonator ring; and a printed circuit board including a plurality of electrical components, the photonic integrated circuit being mounted on a surface of the printed circuit board, the photonic integrated circuit and the printed circuit board being electrically connected. A photonic integrated circuit (PIC) chip including a substrate; a dielectric layer; a first waveguide layer forming at least: a ring resonator and reflector portions; a second waveguide layer forming at least: vertical Bragg grating couplers disposed over one of the plurality of reflector portions, a chip waveguide; a magneto-optic layer encapsulated in the dielectric layer; and a metal layer forming a plurality of metal connection pads and a plurality of wire traces for electrically connecting the PIC chip to electronic components.
