Abstract
A monolithically integrated photonic circuit combining a semiconductor source of excitation light with an optically active waveguide formed on the substrate. The optically active waveguide is preferably formed of a spin-on glass to which are added optically active materials which can enable lasing action, optical amplification, optical loss, or frequency conversion in the waveguide, depending upon the added material.
Claims6
A monolithically integrated solid state optical circuit formed on a semiconductor substrate comprising:
- at least one excitation pump source of light formed on the semiconductor substrate;
- an optical waveguide means on the substrate comprising spun-on glass formed adjacent to and optically coupled to the at least one source of excitation pump light wherein the waveguide means includes a portion containing a dopant material which exhibits optical gain in response to the absorption of radiation from the at least one excitation pump source of light;
- and
- output means optically connected to the waveguide means.
