Abstract: A tunable laser with multiple in-line sections generally includes a semiconductor laser body with a plurality of in-line laser sections each 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 sections may be tuned, in response to a temperature change, to a channel wavelength within the respective wavelength range. A switch module may be configured to couple a signal from a laser driver to a selected one of the plurality of in-line laser sections, wherein the signal modulates the laser light generated by the in-line laser section. The selected in-line section may be DC biased to a lasing state and the non-selected in-line sections may be DC biased to a non-lasing or transparent state.

Abstract: A multi-channel optical transceiver includes a transmitter optical subassembly (TOSA) with a thermal arrayed waveguide grating (AWG) for multiplexing optical signals and a receiver optical subassembly (ROSA) with an athermal AWG for demultiplexing optical signals. The TOSA may also include a laser array optically coupled to the thermal AWG and a temperature control system thermally coupled to the laser array and the thermal AWG to control temperature for wavelength tuning. The temperature control system in the TOSA may include a thermoelectric cooler (TEC) that cools both the laser array and the thermal AWG. Because the athermal AWG in the ROSA is temperature independent, the ROSA does not include a TEC, thereby reducing power consumption and conserving space. The optical transceiver may be used in a wavelength division multiplexed (WDM) optical system, for example, in an optical line terminal (OLT) in a WDM passive optical network (PON).

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 multi-channel optical transceiver includes a multi-channel transmitter optical subassembly (TOSA), a multi-channel receiver optical subassembly (ROSA), and a dual fiber type direct link adapter directly linked to the multi-channel TOSA and the multi-channel ROSA with optical fibers. The dual fiber type direct link adapter is also configured to receive pluggable optical connectors, such as LC connectors, mounted at the end of fiber-optic cables including optical fibers for carrying optical signals to and from the transceiver. The dual fiber type direct link adapter thus provides the optical input and output to the transceiver for the optical signals received by the ROSA and transmitted by the TOSA. The multi-channel optical transceiver may be used in a wavelength division multiplexed (WDM) optical system, for example, in an optical line terminal (OLT) in a WDM passive optical network (PON).

Abstract: A heated laser package generally includes a laser diode, a heating resistor and a transistor in a single laser package. The heating resistor and transistor form a heating circuit and may be located on a submount adjacent to the laser diode. The transistor is configured to control the drive current to the heating resistor and any additional heat generated by the transistor may contribute to the heating of the laser diode and thus increase the thermal efficiency of the system. The heated laser package may be used in a temperature controlled multi-channel transmitter optical subassembly (TOSA), which may be used in a multi-channel optical transceiver. The optical transceiver may be used in a wavelength division multiplexed (WDM) optical system, for example, in an optical line terminal (OLT) in a WDM passive optical network (PON).
