Abstract:
A method of generating an optical signal, comprising:providing a diode laser assembly including an epitaxial structure formed on a substrate, a laser and an amplifier formed in the epitaxial structure, the laser including first and second reflectors, a gain section and a phase section, the gain section and the phase section each being positioned between the first and second reflectors to produce a tunable laser output therefrom, at least a portion of the laser and an amplifier sharing a common waveguide formed in the epitaxial structure, wherein at least a portion of the common waveguide is curved to reduce reflections from an output facet; coupling the laser output into the amplifier along the common waveguide; and generating an optical signal from the amplifier in response to the coupled laser output.
