Patent number: 7167651Abstract: A system for optical communication forms a family of orthogonal optical codes modulated by a data stream. The orthogonal codes are formed by creating a stream of evenly spaced-apart pulses using a pulse spreader circuit and modulating the pulses in amplitude and/or phase to form a family of orthogonal optical code words, each representing a symbol. A spreader calibration circuit is used to ensure accurate timing and modulation. Each code word is further modulated by a predetermined number of data bits. The data modulation scheme splits a code word into H and V components, and further processes the components prior to modulation with data, followed by recombining with a polarization beam combiner. The data-modulated code word is then sent, along with others to receiver. The received signal is detected and demodulated with the help of a symbol synchronization unit which establishes the beginning and end of the code words.Type: GrantFiled: September 26, 2001Date of Patent: January 23, 2007Assignee: CeLight, Inc.Inventors: Isaac Shpantzer, Michael Tseytlin, Yaakov Achiam, Aviv Salamon, Israel Smilanski, Olga Ritterbush, Pak Shing Cho, Li Guoliang, Jacob Khurgin, Yehouda Meiman, Alper Demir, Peter Feldman, Peter Kinget, Nagendra Krishnapura, Jaijeet Roychowdhury, Joseph Schwarzwalder, Charles Sciabarra

Patent number: 7076169Abstract: A system for optical communication send optical signals over a plurality of wavelength channels. Each wavelength channel comprises a number of orthogonal subchannel frequencies which are spaced apart from one another by a predetermined amount. Each of the subchannel frequencies is modulated with data from a data stream. The data modulation scheme splits a subchannel frequency code into H and V components, and further processes the components prior to modulation with data. The various data-modulated subchannels are then combined into a single channel for transmission. The received signals are detected and demodulated with the help of a symbol timing recovery module which establishes the beginning and end of each symbol. A polarization mode distortion compensation module at the receiver is used to mitigate the effects to polarization more distortion in the fiber.Type: GrantFiled: February 28, 2002Date of Patent: July 11, 2006Assignee: CeLight, Inc.Inventors: Isaac Shpantzer, Yehouda Meiman, Michael Tseytlin, Olga Ritterbush, Aviv Salamon, Peter Feldman, Alper Demir, Peter Kinget, Nagendra Krishnapura, Jaijeet Roychowdhury

Patent number: 6671341Abstract: A system for generating a glitch-free output signal having a frequency. The system comprises a frequency divider for receiving a signal having an input frequency, wherein the frequency divider is configured to generate a plurality of corresponding phase-shifted signals.

The retimer is further configured to receive retimer control signals and to generate corresponding multiplexer control signals. The multiplexer is coupled to the retimer and has input terminals configured to receive the multiplexer input signals. The multiplexer is controlled by the multiplexer control signals so as to alternately and successively provide at its output terminal one of the multiplexer input signals.Type: GrantFiled: September 17, 1999Date of Patent: December 30, 2003Assignee: Agere Systems, Inc.Inventors: Peter Kinget, Nagendra Krishnapura
