    Abstract: The present disclosure is generally directed to a transmitter optical subassembly (TOSA) having a hermetically-sealed housing with a feedthrough device that electrically isolates RF and power traces. In more detail, a TOSA consistent with the present disclosure includes a substrate with driving circuitry disposed thereon. A first end of the substrate may electrically couple to transmit connecting circuitry and a second end may couple to a hermetically-sealed housing. The hermetically-sealed housing can include one or more laser packages for emitting associated channel wavelengths in addition to monitor photodiodes (PDs), and temperature control devices such as TECs. The hermetic-sealed housing includes a first end with a feedthrough device that provides traces to electrically couple to the circuitry of the substrate. The hermetic-sealed housing further includes an optical coupling port, e.g., a LC connector, for coupling to an external fiber, for example.

    Abstract: A transceiver module having a partitioned housing, e.g., a bifurcated or multi-segment housing, is disclosed that allows coupling and alignment of a TOSA arrangement and ROSA arrangement in separate respective portions in order to minimize or otherwise reduce component damage and rework iterations during manufacturing and repair. Technicians may thus perform at least partial assembly and testing of each optical subassembly arrangement in parallel and in relative isolation without necessarily interrupting and/or waiting on completion of the other. In a general sense, each separate portion of the partitioned housing provides a dedicated workspace of about equal dimension for coupling of subassembly components. Each separate portion may lie flat on a tabletop, for instance, which may further simplify manufacturing processes and provide a wide-range of acceptance angles for performing soldering, welding, insertion and coupling of components, visual inspection, fiber routing, and so on.

    Abstract: A coaxial transmitter optical subassembly (TOSA) with optical isolator alignment correction may be used in an optical transceiver for transmitting an optical signal at a channel wavelength. The coaxial TOSA includes an optical fiber coupling receptacle extending from a laser package. The laser package may include a laser diode and a lens to focus laser light emitted from the laser diode onto an optical fiber. The laser diode and lens are aligned along a first longitudinal axis of the laser package parallel to a transmission path of the laser light. An optical isolator located in the transmission path is aligned along a second longitudinal axis of the laser package. The second longitudinal axis is coincident with a centerline of the laser package, and the first longitudinal axis is offset from the second longitudinal axis by a predetermined offset distance to compensate for light shifting characteristics of the isolator.

    Abstract: An optical sub-assembly cartridge for use in a multi-channel receiver optical sub-assembly (ROSA) is disclosed and includes pre-aligned demultiplexing optics. 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 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).

The epoxy may be configured to provide an index of refraction that is matched to the optical demultiplexer.

    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).

    Abstract: A temperature controlled multi-channel transmitter optical subassembly (TOSA) may be used in a multi-channel optical transceiver. The temperature controlled multi-channel TOSA generally includes an array of lasers optically coupled to an optical multiplexer, such as an arrayed waveguide grating (AWG), to combine multiple optical signals at different channel wavelengths. The lasers may be thermally tuned to the channel wavelengths by establishing a global temperature for the array of lasers and separately raising local temperatures of individual lasers in response to monitored wavelengths associated with the lasers. A temperature control device, such as a TEC cooler coupled to the laser array, may provide the global temperature and individual heaters, such as resistors adjacent respective lasers, may provide the local temperatures. 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).
