May 8, 2006
Appl. No.:
11/429686
Inventors:
Ronald C. Menendez - Chatham NJ,
Assignee:
Telcordia Technologies, Inc. - Piscataway NJ
International Classification:
H04J 14/00
H04B 10/04
H04L 9/00
US Classification:
398 77, 398188, 380256
Abstract:
The invention is directed toward a variable spectral phase encoder. The variable spectral phase encoder includes a plurality of switches and at least one encoder.

The apparatus comprises a spectral phase decoder for decoding the encoded optical signal to produce a decoded signal, a time gate for temporally extracting a user signal from the decoded signal, and a demodulator that is operable to extract user data from the user signal. The system preferably comprises a source for generating a sequence of optical pulses, each optical pulse comprising a plurality of spectral lines uniformly spaced in frequency so as to define a frequency bin, a data modulator associated with a subscriber and operable to modulate the sequence of pulses using subscriber data to produce a modulated data signals and a Hadamard encoder associated with the data modulator and operable to spectrally encode the modulated data signal to produce an encoded data signal.

Optical Code-Routed Networks

US Patent:
7773882, Aug 10, 2010
Filed:
May 26, 2005
Appl. No.:
11/137938
Inventors:
Ronald Charles Menendez - Chatham NJ,
Assignee:
Telcordia Technologies, Inc. - Piscataway NJ
International Classification:
H04J 14/00
US Classification:
398 78, 398 77, 398 61, 398 49, 398 63, 370 92, 370 93, 370 18, 370 19, 375 25, 375 68, 385 24, 385 37, 385 16, 385 17, 385 18
Abstract:
Communication is provided between at least two of a plurality of stations. A signal is received from a first one of the plurality of stations, and the signal is coded using a first code that is assigned to that station. The coded signal is converted to obtain a further coded signal that is decodable using a further code that is assigned to at least a second one of the plurality of stations. The further coded signal is transmitted for delivery to at least the second one of the plurality of stations.

Code Grouping For Optical Networks

US Patent:
7778547, Aug 17, 2010
Filed:
Jun 1, 2006
Appl. No.:
11/444764
Inventors:
Ronald Charles Menendez - Chatham NJ,
Assignee:
Telcordia Technologies, Inc. - Piscataway NJ
International Classification:
H04J 4/00

Multi-Bit Cryptographically Secure Encryptor For M-Ary Spectral Phase Encoder Optical Code Division Multiple Access

US Patent:
8406423, Mar 26, 2013
Filed:
Mar 16, 2010
Appl. No.:
12/724617
Inventors:
Ronald Charles Menendez - Chatham NJ,
Assignee:
Telcordia Technologies, Inc. - Piscataway NJ
International Classification:
H04K 9/28
US Classification:
380 28, 398201
Abstract:
A system and methods are provided for transmitting an encrypted data word of two or more bits. This involves identifying a random key word comprising two or more bits for encrypting the data word and identifying a set of unique orthogonal codes. This also involves selecting a code from the set of unique orthogonal codes that corresponds to a result of an exclusive-or (XOR) operation between the two or more bits of the data word and the random key word. This also involves encoding a signal with the code and transmitting the encoded signal as encrypted data.

Systems And Methods For Photonically Assisted Rf Filtering

US Patent:
8472806, Jun 25, 2013
Filed:
Apr 24, 2008
Appl. No.:
12/109047
Inventors:
Ted Woodward - Holmdel NJ,
Thomas Banwell - Howell NJ,
Ronald Charles Menendez - Chatham NJ,
Assignee:
Telcordia Technologies, Inc. - Piscataway NJ
International Classification:
H04B 10/00
US Classification:
398115
Abstract:
Systems and methods for improved photonically-assisted RF filtering. Presently, processing of wide-band RF signals involves the use of multiple specialized equipment to isolate a region of interest from the spectrum. The present invention discloses the use of a modulation system to upconvert the RF signal onto the sideband of a light source such as a laser, an optical filter sub-system comprising a plurality of filtering units that function as combinations of IIR and FIR filters, and a resonant channelizing filter for noise reduction and rejection of undesired channels, and means for control and agility of a piecewise coherent optical filter. The resulting filtered RF signal may then be downconverted to the electrical domain for further signal processing.
