    Abstract: In general, a TOSA consistent with the present disclosure includes a light driving circuit coupled to a hermetically-sealed light engine. The hermetically-sealed light engine includes a housing defined by a plurality of sidewalls. The housing defines a cavity that is hermetically-sealed to prevent introduction of contaminants that would otherwise reduce optical power. The hermetically-sealed light engine optically couples to an external arrayed waveguide grating (AWG), or other multiplexing device, by way of an optical receptacle. The optical receptacle can include a waveguide implemented external to the hermetically-sealed cavity and can include, for instance, an optical isolator, fiber stub, and fiber ferrule section. Thus, the external AWG and associated external optical coupling components advantageously allow for the hermetically-sealed light engine to have a cavity with dimensions relatively smaller than other approaches that dispose an AWG and associated components within a hermetically-sealed cavity.

    Abstract: A coaxial transmitter optical subassembly (TOSA) including a ball lens may be used in an optical transceiver for transmitting an optical signal at a channel wavelength. The coaxial TOSA includes a laser package with a ball lens holder section defining a lens holder cavity that receives the ball lens. The lens holder cavity is dimensioned such that the ball lens is positioned in substantial alignment with the laser diode for optically coupling a laser output from the laser diode into an optical waveguide at an optical coupling end of the TOSA. The coaxial TOSA is thus configured to allow the less expensive ball lens to be used in a relatively small package when a lower coupling efficiency and power is desired and without substantial redesign of the TOSA.

    Abstract: A multi-channel receiver optical subassembly (ROSA) including at least one sidewall receptacle configured to receive and electrically isolate an adjacent multi-channel transmitter optical subassembly (TOSA) is disclosed. The multi-channel ROSA includes a housing with at least first and second sidewalls, with the first sidewall being opposite the second sidewall and including at least one sidewall opening configured to fixedly attach to photodiode assemblies. The second sidewall includes at least one sidewall receptacle configured to receive at least a portion of an optical component package, such as a transistor outline (TO) can laser package, of an adjacent multi-channel TOSA, and provide electrical isolation between the ROSA housing and the TOSA within an optical transceiver. The sidewall receptacle can include non-conductive material in regions that directly or otherwise come into close proximity with the optical component package of the adjacent TOSA.

    Abstract: A thermally isolated multi-channel transmitter optical subassembly (TOSA) may be used in a multi-channel optical transceiver. The multi-channel TOSA generally includes an array of lasers optically coupled to an arrayed waveguide grating (AWG) to combine multiple optical signals at different channel wavelengths. The lasers, and possibly other components, are wire bonded to a thermal isolation bar. The thermal isolation bar provides an electrical connection to external circuitry and is thermally coupled to a temperature control device, such as a thermoelectric cooler (TEC). Thus, the thermal isolation bar electrically connects the lasers to the circuitry while preventing external heat from being conducted to the lasers from outside the TOSA. 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: Individual channels of a multiplexed laser array in a multi-channel optical transmitter are monitored at an output of an optical multiplexer. The monitoring may be used to confirm proper operation of each of the channels in the multiplexed laser array and/or to perform wavelength locking on each of the channels. Monitoring at the output of the optical multiplexer avoids the use of multiple photodetectors coupled directly to multiple lasers in the multiplexed laser array. The multiplexed laser array generally includes a plurality of laser emitters optically coupled to an optical multiplexer such as an arrayed waveguide grating (AWG). An optical transmitter with a monitored multiplexed laser array may be used, for example, in an optical line terminal (OLT) in a wavelength division multiplexed (WDM) passive optical network (PON) or in any other type of WDM optical communication system capable of transmitting optical signals on multiple channel wavelengths.

    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).
