Abstract: An optical transceiver assembly includes a thermal dual arrayed waveguide grating (AWG) for both multiplexing and demultiplexing optical signals. The thermal dual AWG may be used as an optical multiplexer/demultiplexer with an array of laser emitters and an array of photodetectors to provide a transmitter optical subassembly (TOSA) and a receiver optical subassembly (ROSA) in the optical transceiver assembly. The thermal dual AWG may be formed as a single chip, and a temperature control device, such as thermoelectric cooler (TEC), may be used in the transceiver to stabilize the temperature of the AWG. In an embodiment, an external reflector may be used at a transmit output of the dual AWG to complete the lasing cavities after the AWG, thereby providing a laser array mux assembly. The optical transceiver device may also be part of a larger system, such as a wavelength division multiplexed (WDM) passive optical network (PON).

Abstract: An arrayed waveguide grating (AWG) device for use in an optical transceiver is disclosed, and can de-multiplex an optical signal into N number of channel wavelengths. The AWG device can include an AWG chip, with the AWG chip providing a planar lightwave (PLC) circuit configured to de-multiplex channel wavelengths and launch the same into output waveguides. A region of the AWG chip may be tapered such that light traveling via the output waveguides encounters an angled surface of the tapered region and reflects towards an output interface region of the AWG chip. Thus detector devices may optically couple to the output interface region of the AWG chip directly, and can avoid losses introduced by other approaches which couple an output of an AWG to detectors by way of a fiber array or other intermediate device.

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. The laser light generated in each selected one of the laser sections is emitted from a front facet of the laser body. By selectively generating light in one or more of the laser sections, one or more channel wavelengths may be selected for lasing and transmission. The tunable laser with multiple in-line sections may be used, for example, in a tunable transmitter in an optical networking unit (ONU) in a WDM passive optical network (PON) to select a transmission channel wavelength.

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 transmitter optical subassembly (TOSA) with an off-center fiber in an optical coupling is disclosed, and can provide passive compensation for beam displacement introduced by optical isolators. The optical coupling receptacle can include an optical isolator configured to receive a focused light beam from a focus lens within the TOSA. The optical coupling receptacle may be offset such that a center line of the focused light beam entering the optical isolator is offset from a center line of a fiber within optical coupling receptacle. Thus the optical isolator receives the focused light beam from the focus lens and introduces beam displacement such that an optical signal is launched generally along a center line of the fiber. Thus the expected beam displacement introduced by the optical isolator is eliminated or otherwise mitigated by the offset between a center line of the fiber and a center position of the focus lens.

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.
