Wide Band Digital Receiver: System And Method

View page
US Patent:
8442402, May 14, 2013
Filed:
Aug 5, 2011
Appl. No.:
13/204158
Inventors:
Raymond Zanoni - Columbia MD, US
Oliver S. King - Frederick MD, US
Kim S. Jepsen - Ellicott City MD, US
Assignee:
Rockwell Collins, Inc. - Cedar Rapids IA
International Classification:
H04B 10/00
US Classification:
398115, 398202, 341137
Abstract:
A wide band digital RF receiver includes an RF front end configured to convert a RF signal into an IF signal. A wide band digital receiver also includes a photonic Analog-to-Digital Converter (pADC), and a digital processor. The pADC includes a photonic sampler that phase-encodes a stream of optical pulses with the IF signal to obtain phase-encoded optical pulses, and that amplitude-encodes an identical stream of optical pulses with the IF signal to obtain amplitude-encoded optical pulses. The pADC also includes a photonic processor and an electronic quantizer. The photonic processor processes the phase-encoded optical pulses by way of an I channel and a Q channel, and processes the amplitude-encoded optical pulses by way of an amplitude channel.

Optical Deserialization With Gated Detectors: System And Method

View page
US Patent:
8456336, Jun 4, 2013
Filed:
Sep 22, 2011
Appl. No.:
13/240226
Inventors:
Raymond Zanoni - Columbia MD, US
Kim S. Jepsen - Ellicott City MD, US
Mark A. Laliberte - Crownsville MD, US
Oliver S. King - Frederick MD, US
Assignee:
Rockwell Collins, Inc. - Cedar Rapids IA
International Classification:
H03M 1/12
US Classification:
341137, 395202
Abstract:
A method of performing optical serial-to-parallel conversion of an optical signal includes performing phase modulation of the optical pulse stream and outputting a phase-modulated optical signal. Optical switching of the phase-modulated optical signal is performed by optical switches provided on a signal path. Optical switching of a reference optical clock signal is performed by optical switches provided on a reference path. I/Q demodulation of the optically switched phase-modulated optical signal respectively output by an optical switch is performed on the signal path at timings corresponding to the optically switched reference optical clock signal respectively output by an optical switch on the reference path, in which I and Q demodulated signals are output as a result thereof. Photodetection of the I and Q demodulated signals is then performed.

Systems And Methods For Reducing Mechanical Sensitivity Of Phase Sensitive Optical Signals

View page
US Patent:
8478132, Jul 2, 2013
Filed:
Jun 21, 2010
Appl. No.:
12/819481
Inventors:
Kim S. Jepsen - Ellicott City MD, US
Raymond Zanoni - Collumbia MD, US
Mark A. La Liberte - Columbia MD, US
Alistair J. Price - Ellicott MD, US
Peter J. Morgan - Gleneig MD, US
Assignee:
Rockwell Collins, Inc. - Cedar Rapids IA
International Classification:
H04B 10/00
H04B 10/12
US Classification:
398152, 398184, 398205
Abstract:
The present invention is an optical system configured for enabling co-transmission (ex. —co-propagation) of a reference signal and a carrier signal (ex. —or a phase encoded signal and a reference signal) in a same fiber. Since it is configured for enabling said co-transmission, the optical system of the present invention promotes reduced transmission microphonic sensitivity in the optical system.

Optically Interleaved Electronic Analog To Digital Converters

View page
US Patent:
8548331, Oct 1, 2013
Filed:
Sep 23, 2011
Appl. No.:
13/243208
Inventors:
Raymond Zanoni - Columbia MD, US
Kim S. Jepsen - Ellicott City MD, US
Oliver S. King - Frederick MD, US
Mark A. Laliberte - Crownsville MD, US
Assignee:
Rockwell Collins, Inc. - Cedar Rapids IA
International Classification:
H04B 10/00
US Classification:
398115, 398202
Abstract:
An analog signal receiver includes photonic sampling and electronic quantization. The receiver includes timing control circuitry configured to receive a series of optical pulses and output a plurality of timing signals based on the series of optical pulses to synchronize optical switches that receive a sampled optical signal to time deinterleave the optically sampled signal. The time deinterleaved signals are then sent to a plurality of demodulators wherein each demodulator receives at least one time deinterleaved optically sampled signal and at least one time deinterleaved optical reference signal to produce electrical signals based on the demodulated optical signals.

Distributed Raman Amplification System

View page
US Patent:
20030011875, Jan 16, 2003
Filed:
Mar 14, 2002
Appl. No.:
10/099530
Inventors:
Stuart Gray - Corning NY, US
Kim Jepsen - Ellicott City MD, US
Michael Vasilyev - Belle Mead NJ, US
International Classification:
H01S003/00
US Classification:
359/334000
Abstract:
In a distributed Raman amplification system, the pump laser and the fiber are chosen so as to have characteristics which result in broadening of the DRBS. For example, with a transmission fiber through which signal light of a wavelength propagates, and having zero dispersion at a wavelength ; a pump laser producing counterpropagating pump light at a wavelength ; where and are on opposite sides of the zero dispersion wavelength is used. The transmission fiber may be large effective area fiber. In a Raman amplification system suitable for use in a WDM optical fiber communication system, pump lasers having mode spacing which is less than the optical bandwidth of the signal channel have been found to be advantageous.
