Abstract
A waveguide optical gyroscope (WOG) is disclosed. One WOG may comprise an amplified spontaneous emission (ASE) source, a sensor comprising a waveguide loop disposed in a first cladding material interposed between layers of at least a second cladding material having an index of refraction lower than an index of refraction of the first cladding material, wherein the sensor is configured to receive an output signal of the ASE source, and a pump source configured to pump the first cladding material with an in-plane pump signal.
