  • Patent number: 10281746
    Abstract: An optical transmitter includes a reflective semiconductor optical amplifier (RSOA) coupled to an input end of a first optical waveguide. An end of the first optical waveguide provides a transmitter output for the optical transmitter. Moreover, a section of the first optical waveguide between the input end and the output end is optically coupled to a ring modulator that modulates an optical signal based on an electrical input signal. A passive ring filter (or a 1×N silicon-photonic switch and a bank of band reflectors) is connected to provide a mirror that reflects light received from the second optical waveguide back toward the RSOA to form a lasing cavity. Moreover, the ring modulator and the passive ring filter have different sizes, which causes a Vernier effect that provides a large wavelength tuning range for the lasing cavity in response to tuning the ring modulator and the passive ring filter.

  • Patent number: 10254625
    Abstract: An optical signal processing device with a transponder aggregator function by which theoretical loss is not increased even if the number of necessary transponders is increased. Optical signals inputted from input ports are inputted to a PLC. The PLC has SBTs. The input ports are connected to the input-end SBT, and a plane wave is outputted from an output end of the PLC to the space side at an angle different for each input port. Optical signals outputted by the PLC are changed in their optical paths on the x-z plane by a cylindrical lens (Lsp) designed to refract optical signals in the x-axis direction, and are reflected by an LCOS at different regions corresponding to the positions of the input port. The reflected optical signals are incident on the output-end SBTs on the PLC, and are outputted to output ports via demultiplex parts.

  • Patent number: 10247892
    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.
