Use Of Bandwidth Efficient Modulation Techniques In A Wavelength Division Multiplexed Optical Link

View page
US Patent:
6407837, Jun 18, 2002
Filed:
Nov 25, 1998
Appl. No.:
09/200029
Inventors:
Ralph Spickermann - Redwood City CA
Assignee:
Lockheed Martin Corporation - Bethesda MD
International Classification:
H04J 1402
US Classification:
359124, 359162
Abstract:
Systems and methods that improve data transmission over a wavelength division multiplexed optical link. First and second wavelength division multiplexed modulators modulate data for transmission onto a microwave carrier signal to produce first and second carrier signals having a first carrier frequency. A downconverter downconverts the first carrier signal to a lower carrier frequency. A combiner combines the downconverted and second carrier signals to provide a composite microwave signal. A wavelength division multiplexed transmitter transmits the composite microwave signal on a wavelength division multiplexed channel over an optical fiber. A wavelength division multiplexed receiver reproduces the composite microwave signal transmitted over the optical fiber. A splitter and filters separate out the downconverted and second carrier signals from the composite microwave signal. An upconverter upconverts the downconverted carrier signal from the lower carrier frequency to the first carrier frequency.

Use Of Higher Order Modulation Techniques To Transmit Large Aggregate Data Rates On An Optical Link With Relatively Low Speed Electronics

View page
US Patent:
6522697, Feb 18, 2003
Filed:
Feb 11, 1999
Appl. No.:
09/248420
Inventors:
Ralph Spickermann - Redwood City CA
Assignee:
Lockhead Martin Corporation - Bethesda MD
International Classification:
H03K 906
US Classification:
375271, 359126
Abstract:
Systems and methods that increase the maximum data rate capacity per optical carrier on an optical link. The present invention intensity modulates an optical carrier with one or more (microwave) carriers that have been higher order modulated (M-ary ASK, PSK, QAM, and the like) using bandwidth efficient modulation. Consequently, as the number of bits/symbol is increased, the bit rate increases without an increase in occupied bandwidth. Thus, 2 bit/Hz or more of optical channel bandwidth may be transmitted.

Bandwidth Efficient Phase Shift Keyed Modulation Over Nonlinear Distortion Limited Optical Fiber Links

View page
US Patent:
6590683, Jul 8, 2003
Filed:
Feb 4, 1999
Appl. No.:
09/245160
Inventors:
Ralph Spickermann - Redwood City CA
Assignee:
Lockheed Martin Corporation - Bethesda MD
International Classification:
H04B 1000
US Classification:
359161, 359188, 359180, 359124, 359133, 330149, 327317, 327318, 327355, 327356, 327362
Abstract:
Systems and methods that increase the data transmission rate through a given length of optical fiber, or increase the distortion-limited distance for an optical fiber link at a given data rate using band efficient modulation. This is achieved by modulating data for transmission onto a carrier signal. The modulated signal is predistorted and an optical carrier is amplitude modulated using the predistorted signal. The amplitude modulated optical carrier is transmitted over the optical fiber link. The original modulated microwave signal is reproduced at a receiver. The original signal is demodulated to generate the originally transmitted data. In addition, to reduce the bandwidth required by the modulated carrier, it may be single-sideband modulated. By increasing the number of bits per symbol and keeping the symbol rate constant, the data rate for a given length of optical fiber may be increased using the present invention without introducing additional distortion in the fiber.

Optically Induced Total Internal Reflection X-Junction Waveguide Optical Switch, Network And Optical Switching Method

View page
US Patent:
6847741, Jan 25, 2005
Filed:
Oct 4, 2002
Appl. No.:
10/264609
Inventors:
Steven R. Sakamoto - Santa Clara CA, US
Ralph Spickermann - Redwood City CA, US
Assignee:
Lockheed Martin Corp - Bethesda MD
International Classification:
G02B 626
G02F 1313
US Classification:
385 5, 385 45, 385 22
Abstract:
Optical apparatus and optical switching methods that provide optical high data rate switching at a wavelength or packet level using optical tone addressing. Optical signal routing is a result of optically induced total internal reflection at the intersection of an X-junction waveguide structure. The total internal reflection effect is controlled by a high intensity optical pump beam separate from the optical data signal. Total internal reflection may result from a free-carrier induced change in refractive index, which is a nonlinear effect found in common III-V semiconductors and selected polymers. Optical switching networks may be formed using cascaded pluralities of optical waveguide switches.

Optical Memory And Logic Using Cross-Switches

US Patent:
6963677, Nov 8, 2005
Filed:
Nov 25, 2003
Appl. No.:
10/722223
Inventors:
Ralph Spickermann - Redwood City CA, US
Steven R. Sakamoto - Santa Clara CA, US
Assignee:
Lockheed Martin Corp. - Bethesda MD
International Classification:
G02B006/26
G11C013/04
G02F003/00
US Classification:
385 16, 385 1, 385 15, 385 18, 385 24, 385 14, 365 64, 359108, 359107
Abstract:
An all-optical, asynchronous binary storage cell implemented by optically induced total internal reflection cross-junction waveguide switches. The term “all-optical” refers to directing of optical data signals as a result of optical control signal inputs without the need for conversion between optical and electrical domains. The binary cell is a building block for a programmable all-optical random access memory (AORAM) device. The AORAM device enables circuits and networks that require optical buffers.

Programmable Optical Vector Modulator And Method For Use In Coherent Optical Communications

View page
US Patent:
7085500, Aug 1, 2006
Filed:
Apr 30, 2001
Appl. No.:
09/845557
Inventors:
Ralph Spickermann - Redwood City CA, US
Assignee:
Lockheed Martin Corp. - Bethesda MD
International Classification:
H04B 10/04
US Classification:
398185, 398183, 398193, 398188
Abstract:
A transmitter comprising a programmable optical vector modulator and method for coherent optical signal communication. The transmitter includes a transmitter laser whose output is coupled by way of an optical fiber to an amplitude modulator. The output of the amplitude modulator is coupled by way of a length of optical fiber to a phase modulator. The phase modulator generates a modulated light output from the transmitter. Amplitude modulation is achieved by inputting data and a data clock signal to amplitude symbol mapping logic whose outputs are selectively weighted, summed, amplified and input to the amplitude modulator to amplitude modulate the output of the transmitter laser. Phase modulation is achieved by inputting the modulating data and the data clock signal to phase angle symbol mapping logic whose outputs are selectively weighted, summed, amplified, delayed to synchronize with the arrival of the light from the amplitude modulator, and input to the phase modulator to phase modulate the amplitude modulated output of the transmitter laser. The programmability of the vector modulator allows the transmission of an M-ary modulation format that maximizes the data transmission for a given optical dynamic range and bit error rate target. Also, the programmability allows for rapid change in modulation format to maximize data transmission for changes in optical dynamic range and bit error rate target.

All Optical Time Division Multiplexer And Packet Switch Using Optical Codewords And Optically Actuated Optical Switches

View page
US Patent:
7260329, Aug 21, 2007
Filed:
Sep 1, 2004
Appl. No.:
10/932223
Inventors:
Thomas C. Fall - Los Gatos CA, US
Ralph Spickermann - Redwood City CA, US
Daniel A. Tauber - Palo Alto CA, US
Assignee:
Lockheed Martin Corporation - Bethesda MD
International Classification:
H04J 14/08
H04J 14/00
H04B 10/04
US Classification:
398102, 398 52, 398 98, 398182
Abstract:
Optical apparatus that uses optically-actuated optical switches in conjunction with an optical codeword addressing scheme to provide for time division multiplexing and demultiplexing of high data rate optical data. Optical codewords traveling simultaneously with the data on a separate wavelength, in conjunction with the optical switches, enable all-optical multiplexing and demultiplexing. The present invention can also switch packets of data while keeping the data entirely in the optical domain, and no optical to electrical conversions are necessary.

Subliminal Coherent Phase Shift Keyed In-Band Signaling Of Network Management Information In Wavelength Division Multiplexed Fiber Optic Networks

View page
US Patent:
20030043437, Mar 6, 2003
Filed:
Sep 4, 2001
Appl. No.:
09/947010
Inventors:
Stephen Stough - Campbell CA, US
Ralph Spickermann - Redwood City CA, US
International Classification:
H04B010/12
H04B010/04
US Classification:
359/173000, 359/183000
Abstract:
Optical communication systems and methods that provide subliminal in-band signaling of network management information in coherent phase shift keyed (PSK) optical networks. The advantages of this method over various prior art are twofold: (1) It does not require an extra wavelength division multiplexed optical channel to transmit network management data, and (2) it does not require expensive complete time division demultiplexing of the payload data to extract the network management information. The management channel data is transmitted in a spread spectrum signal format that is below the limit of detection in the transmission channel, hence the term subliminal. The subliminal signal is detected using correlative techniques (despreading). The spread-spectrum signal is a direct sequence binary PSK representation of the management channel data plus a spreading code. This spread spectrum signal is superimposed as a slow phase modulation on top of the transmitted high speed PSK payload signal. The high speed PSK data signal acts as a carrier of the spread spectrum signal to the receiver. The spread spectrum phase modulation has a deviation that is smaller than the root mean square phase noise in the fiber optic channel, thereby introducing no measurable increase in the required transmission bandwidth. The subliminally transmitted information is recovered using phase detection of the spread spectrum signal plus noise followed by a conventional despreading operation to raise the signaling information above the level of the received phase noise. The subliminally transmitted management channel info may be recovered at intermediate points in the fiber optic network without expensive complete electronic time division demultiplexing.
