摘要： An optical transceiver module for use in optical communications networks is disclosed. The transceiver features a simplified optical subassembly structure that facilitates the alignment and calibration of active optical components located thereon. The transceiver includes a shell that contains a transceiver printed circuit board and a transmitter/receiver optical subassembly (“TROSA”) connected to the printed circuit board via a TROSA connector. The TROSA includes a singular substrate on which a laser for producing optical signals and a photodetector for receiving optical signals are disposed. The laser and photodetector are precisely positioned on the TROSA substrate to have a specified spacing therebetween. So positioned, the laser and photodetector can be aligned with conduits of a sleeve assembly in a single alignment operation, thereby simplifying calibration of the transceiver module. The present transceiver eliminates the use of multiple substrates separately supporting the laser and the photodetector, thus also eliminating related alignment challenges.

摘要： Methods for assembly of optical transceivers. In one example, the method is performed in connection with an optical transceiver that includes a transmitter optical subassembly and a receiver optical subassembly, as well as structure that defines a pair of ports with which the transmitter optical subassembly and receiver optical subassembly, respectively, are to be aligned. This example of the method involves positioning the transmitter optical subassembly and the receiver optical subassembly in a desired position relative to each other. The transmitter optical subassembly and the receiver optical subassembly are then fixed in the desired position. Next, the transmitter optical subassembly is aligned with one of the ports, and the receiver optical subassembly is aligned with the other port. The alignment of both the transmitter optical subassembly and the receiver optical subassembly with their respective ports is performed in a single operation.

摘要： In one example, an optical subassembly positioning plate is provided that includes a substantially flat body that defines at least one edge. A port is defined in the body. The port is configured to receive and secure an optical subassembly in an x-direction and a y-direction when said optical subassembly positioning plate is positioned within an optoelectronic transceiver module. A plurality of fingers is defined along at least one edge of the body. Each of the plurality of fingers is configured to contact a shell of the optoelectronic transceiver module so as to bias a flange of the optical subassembly against a portion of the shell of the optoelectronic transceiver module such that the optical subassembly is substantially retained in a z-direction when the optical subassembly positioning plate is positioned within the optoelectronic transceiver module.

摘要： An apparatus consisting of stacked slab waveguides whose outputs are vertically staggered is disclosed. At the input to the stacked waveguides, the entrances to each slab lie in approximately the same vertical plane. A spot which is imaged onto the input will be transformed approximately to a set of staggered rectangles at the output, without substantial loss in brightness, which staggered rectangles can serve as a convenient input to a spectroscopic apparatus. A slit mask can be added to spatially filter the outputs so as to present the desired transverse width in the plane of the spectroscopic apparatus parallel to its dispersion.
