Abstract
A resonant fiber optic gyroscope comprises: a ring resonator including a fiber coil fabricated from a first type of hollow core fiber; a light source to produce at least two light beams, wherein a first light beam is configured to travel in a clockwise direction in the ring resonator and a second light beam is configured to travel in a counterclockwise direction in the ring resonator; a filter resonator assembly coupled between the light source and the ring resonator including: at least two short pieces of optical fiber shorter in length than the fiber coil, the at least two short pieces of optical fiber fabricated from the first type of hollow core fiber; and wherein prior to the beams entering the ring resonator, a plurality of reflective devices are configured to condition the beams such that they excite the fundamental mode of the hollow core fiber within the ring resonator.
