  • Optical transceiver with equalization and controllable laser interconnection interface
    Patent number: 8989588
    Abstract: An optical transceiver includes an optical IC coupled to a processor IC. For transmit, the optical IC can be understood as a transmitter IC including a laser device or array. For receive, the optical IC can be understood as a receiver IC including a photodetector/photodiode device or array. For a transmitter IC, the processor IC includes a driver for a laser of the transmitter IC. The driver includes an equalizer that applies high frequency gain to a signal transmitted with the laser device. For a receiver IC, the processor IC includes a front end circuit to interface with a photodetector of the receiver IC. The front end circuit includes an equalizer that applies high frequency gain to a signal received by the receiver IC. The driver can be configurable to receive a laser having either orientation: ground termination or supply termination.

  • APPLYING CONTROLLED IMPEDANCE TO IMPROVE OPTICAL TRANSCEIVER BANDWIDTH
    Publication number: 20130188963
    Abstract: An optical transceiver includes an optical receiver IC coupled to a processor IC. The processor IC includes an integrated optical receiver front end circuit, and includes an integrated inductor to control the LC frequency response of a signal from the optical receiver IC to the output of the front end circuit. The inductor is coupled in series between interface components of the processor IC and an input of the front end circuit. The inductor is configured to adjust an effective input reactance of the front end circuit, which operates to control the LC frequency response of a signal from the optical receiver IC to an output of the front end circuit.
