摘要： A hybrid optical source comprises an optical gain chip containing an optical gain material that provides an optical signal, and an optical reflector chip including an optical reflector. It also includes a semiconductor-on-insulator (SOI) chip, which comprises a semiconductor layer having a planarized surface facing the semiconductor reflector. The semiconductor layer includes: an optical coupler to redirect the optical signal to and from the planarized surface; and an optical waveguide to convey the optical signal from the optical coupler. While assembling these chips, a height of the optical gain material is referenced against the planarized surface of the semiconductor layer, a height of the optical reflector is referenced against the planarized surface of the semiconductor layer, and the optical reflector is aligned with the optical coupler, so that the optical signal emanating from the optical gain material is reflected by the optical reflector and into the optical coupler.

摘要： A tunable laser includes a reflective silicon optical amplifier (RSOA) with a reflective end and an interface end and an array of narrow-band reflectors, which each have a different center wavelength. It also includes a silicon-photonic optical switch, having an input port and N output ports that are coupled to a different narrow-band reflector in the array of narrow-band reflectors. The tunable laser also includes an optical waveguide coupled between the interface end of the RSOA and the input of the silicon-photonic optical switch. The frequency of this tunable laser can be tuned in discrete increments by selectively coupling the input port of the silicon-photonic optical switch to one of the N output ports, thereby causing the RSOA to form a lasing cavity with a selected narrow-band reflector coupled to the selected output port. The tunable laser also includes a laser output optically coupled to the lasing cavity.
