Patent number: 6980747Abstract: An integrated, optically amplified receiver includes an optically pumped optical preamplifier for receiving, generally, wavelength division multiplexed optical communication signal over an optical communications line. A PIN photodetector receives the optical communication signal as a filtered demultiplexed signal from the optical preamplifier and converts the optical communication signal into an electrical communication signal. An amplifier circuit amplifies the electrical communication signal for digital retiming or demodulation. A housing or printed circuit card assembly contains the optical preamplifier, filter or demultiplexer, PIN photo detector and amplifier circuit as an integrated receiver unit.Type: GrantFiled: November 28, 2000Date of Patent: December 27, 2005Assignee: Harris CorporationInventors: John DeSalvo, Michael Lange, Scott Bricker, Randall K.

Patent number: 6748179Abstract: The system and method of the present invention is operative to monitor the performance of an optical communications channel. An optical splitter splits a wavelength division multiplexed (WDM) optical communications signal into a low power WDM signal onto a back-up path, where a tunable filter sweeps the optical communications channels, while a monitoring circuit monitors the optical communications channels for performance. Optical power can be stored and subsequently displayed, providing an optical spectrum analysis of the signal.Type: GrantFiled: March 7, 2001Date of Patent: June 8, 2004Assignee: Harris CorporationInventors: Michael Lange, Edward Tegge, John DeSalvo

Patent number: 6560257Abstract: A laser driver circuit includes an injection laser diode. A current source control loop circuit is connected to the injection laser diode and establishes a fixed current through the injection laser diode. A voltage switcher circuit is connected to the injection laser diode and current source control loop circuit and adapted to receive a fixed supply voltage and convert inductively the supply voltage down to a forward voltage to bias the injection laser diode and produce an optical fiber coupled laser output having minimized power losses.Type: GrantFiled: November 28, 2000Date of Patent: May 6, 2003Assignee: Harris CorporationInventors: John DeSalvo, Michael Lange, Alan Williams
