An optical or optoelectronic transceiver and methods of making the same are disclosed. The transceiver comprises a connector configured to receive an optical fiber array, a filter that is (i) configured to reflect first optical signals having a first wavelength and (ii) transparent to second optical signals having a second wavelength, wherein each of the first and second optical signals independently has an optical path to or from the optical fiber array, a mirror in the optical path of the second optical signals configured to reflect the second optical signals, a plurality of photodiodes configured to receive a subset of the first and/or second optical signals and generate a corresponding plurality of received electrical signals therefrom, and a plurality of laser diodes configured to transmit a remainder of the first and/or second optical signals from a corresponding plurality of transmitted electrical signals.

Optical transceiver and methods of making and using the same

A bidirectional optical subassembly, an optical transceiver including the same, and methods of making and using the same are disclosed. The optical subassembly includes a photodiode configured to receive an incoming optical signal, a transmitter configured to transmit an outgoing optical signal, and a passive optical signal processing unit including a filter and a mirror. The filter is at a first predetermined angle relative to an optical path of the outgoing optical signal and is configured to (i) reflect one of the outgoing optical signal and the incoming optical signal and (ii) allow the other of the outgoing optical signal and the incoming optical signal to pass through. The mirror is configured to reflect the one of the outgoing optical signal and the incoming optical signal at a second predetermined angle. The first predetermined angle is adapted to reduce filter insertion losses.

An integrated lens with integrated functional optical surfaces for use in optical communication is disclosed. The integrated lens includes first and second cavities and a fiber adapter. The device also includes integrated first and second lenses. The first cavity houses one or more optical transmitting and/or receiving devices. The second cavity has a first optical surface and an optional second optical surface. The fiber adapter has the second lens. The integrated lens enables a small size, a light weight, high coupling and a high transmission efficiency, and can be produced by injection molding using a single mold. The integrated lens is applicable to optical signal coupling, fiber connections, optical modules, and optical or optoelectronic communication.

A high speed optical module, and in particular, a multi-channel, single-mode, parallel transmission optical module in the field of optical communication is disclosed. The optical module includes a chassis, a first transmitter optical subassembly (TOSA), a second transmitter optical subassembly (TOSA), a third transmitter optical subassembly (TOSA), a fourth transmitter optical subassembly (TOSA) and a MT fiber connector. The TOSA may be a TO-38 TOSA of a 10 G DFB chip or FP chip. With single-mode communication, the optical module provides a transmission distance over 10 kilometers. In addition, to make coupling single-mode fibers easier, a twelve-core MT fiber connector is employed, wherein four fiber connectors are respectively connected to LC standard fiber stubs and the outputs of the TOSAs accordingly. Thus, the optical module further provides high speed and long-distance transmission, large capacity, small volume, and light weight and can be broadly applied to high speed optical communications.
