Abstract
A tunable optical system with hybrid integrated semiconductor laser is provided. The optical system includes a silicon-on-insulator (SOI) substrate; a first optical waveguide tunable comb filter formed at the first side of the SOI substrate; a second optical waveguide tunable comb filter with detuned filter response formed at the first side of the SOI substrate; an etched laser pit at the first side of the SOI substrate; a plurality of spacers formed on the bottom surface of the laser pit near the plane of the first side of the SOI substrate; a plurality of bumping pads formed on the bottom surface of the laser pit near the plane of the first side of the SOI substrate; and a laser chip flip-chip bonded at the first side of the SOI substrate supported by the spacers. Heating sections may be provided on the filters to tune the filters.
