Abstract:
1. A tunable pulsed laser comprising: a substrate comprising a silicon material and a recess region having an interface; a gain medium coupled to the substrate and having a facet spatially separated from the interface by an index matching region, wherein the gain medium includes a compound semiconductor material; an optical modulator optically coupled to the gain medium, wherein the optical modulator comprises an intracavity optical element; a waveguide disposed in the substrate and optically coupled to the gain medium; a first wavelength selective element characterized by a first reflectance spectrum and disposed in the substrate; a second wavelength selective element characterized by a second reflectance spectrum and disposed in the substrate; an optical coupler disposed in the substrate and joining the first wavelength selective element, the second wavelength selective element, and a phase adjustment section disposed in the silicon material substrate between the waveguide and the optical coupler, the phase adjustment section having a heating element; and an output mirror.
