ABSTRACT:
In a thin film micro-optic gyroscope (MOG) (10) a waveguide resonator structure (14) has an optical transmission path formed within a surface of a substrate (12). In one embodiment the path includes a predetermined amount of dopant (12a) for providing regenerative gain to radiation of a predetermined wavelength propagating through the path. The dopant is provided at a predetermined concentration and is substantially uniformly distributed throughout the path. By example, the substrate is comprised of neodymium-doped glass. A pump source is optically coupled to the path for exciting the dopant to emit radiation, the pump source providing radiation at a wavelength of approximately one-half of the predetermined wavelength. For the example of neodymium-doped glass the predetermined wavelength is 1.06 microns. The resulting regenerative resonator improves the quality of integrated optic resonators used in the MOG by providing a small amount of gain to the resonator to compensate for the optical signal lost by scattering, radiation and absorption.
