The optical sub-assembly cartridge may include a plurality of sidewalls which define a cartridge body and at least partially enclose a cavity therein. A sidewall of the cartridge body may include a sidewall opening configured to allow light to enter the cavity. A first optical filter disposed opposite the sidewall opening may receive light entering the cavity and be configured to pass unassociated channel wavelengths out of the cavity while reflecting associated channel wavelengths to a mirror disposed in the cavity. The mirror may then reflect the received channel wavelengths to a second optical filter within or external to the cavity. The second optical filter may emit a narrow spectrum of channel wavelengths to a photodiode package to convert the same to a proportional electrical signal.

Abstract: A semiconductor laser diode with integrated heating generally includes a lasing region and a heating region integrated into the same semiconductor structure or chip. The lasing region and the heating region include first and second portions, respectively, of the semiconductor layers forming the semiconductor structure and include first and second portions, respectively, of the active regions formed by the semiconductor layers. Separate laser and heater electrodes are electrically connected to the respective lasing and heating regions for driving the respective lasing and heating regions with drive currents. The heating region may thus be driven independently from the lasing region, and heat may be conducted through the semiconductor layers from the heating region to the lasing region allowing the temperature to be controlled more efficiently.

Abstract: A parallel cavity tunable laser generally includes a semiconductor laser body defining a plurality of parallel laser cavities with a common output. Each of the parallel laser cavities is configured to be driven independently to generate laser light at a wavelength within a different respective wavelength range. The wavelength of the light generated in each of the laser cavities may be tuned, in response to a temperature change, to a channel wavelength within the respective wavelength range. The laser light generated in each selected one of the laser cavities is emitted from the common output at a front facet of the laser body. By selectively generating light in one or more of the laser cavities, one or more channel wavelengths may be selected for lasing and transmission.
