Assignee:

All Optical Networks, Inc. - San Diego CA

International Classification:

G02B 2600

US Classification:

359239, 359124, 385 24

Abstract:

A method for photonic wavelength shifting and stabilization is described. The method receives a photonic signal, comprised of one or more channels, and provides a wavelength shifted, stabilized, and channelized photonic signal. Data encoding is also supported. A modulation synthesizer provides a modulation waveform embedded with the shifting, stabilization and data encoding mechanisms. A variety of modulation techniques are supported. The modulation waveform is optimized for the particular modulation technique. A wavelength error detector provides feedback to the modulation synthesizer. The error signal is used to stabilize the photonic signal and correct channel wavelength errors. Fixed wavelength channels and spread spectrum channels are supported.

Appl. No.:

09/872404

Inventors:

Michael Myers - Poway CA, US
Juan Riley - San Diego CA, US
Clark Guest - San Diego CA, US

International Classification:

H04B010/00

US Classification:

359/161000, 359/152000

Abstract:

A method for photonic transceiving spectrally replicates a photonic input signal to provide a replicated photonic signal. The replicated photonic signal contains multiple copies of the photonic input signal shifted to various wavelengths. The replicated photonic signal is then filtered to provide a photonic output signal within a desired passband. The photonic input signal may be spectrally replicated through a variety of mechanisms including four-wave mixing, modulation with a harmonically rich modulation waveform, recursive wavelength-shifting and complementary recursive wavelength-shifting.

Clark Guest - San Diego CA, US

International Classification:

H04J014/02
H04B010/00

US Classification:

359/161000, 359/124000

Abstract:

An apparatus for wavelength-shift multiplexing narrowband filters a composite photonic signal to provide a narrowband signal. The narrowband filtering operates as a channel selector by isolating the narrowband signal from the composite photonic signal. The narrowband signal may be a full-duplex signal with transmit and receive components. The narrowband signal may be wavelength shifted to provide a channelized photonic signal. The present invention is useful as a building block for photonic transmission, switching and multiplexing. Multiple channelized photonic signals may be combined or separated by the present invention.

International Classification:

G02F001/35

US Classification:

359/326000

Abstract:

An apparatus and method for photonic channel allocation is described. A photonic signal, comprised of one or more channels, is received, characterized, and assigned to one or more channels. Once assigned the photonic signal is stabilized and wavelength shifted to occupy one or more channels on the photonic output signal. A modulation synthesizer provides a modulation waveform embedded with the shifting, stabilization and data encoding mechanisms. A variety of modulation devices and techniques are supported. The modulation waveform is optimized for the particular modulation device or technique. A wavelength error detector provides feedback to the modulation synthesizer. The error signal is used to stabilize the photonic signal and correct channel wavelength errors. Fixed wavelength channels and spread spectrum channels are supported.
