Servo-Stabilized-Phase, Differential Coherence Detector

US Patent:
6407848, Jun 18, 2002
Filed:
Dec 27, 2000
Appl. No.:
09/753504
Inventors:
Arkady S. Bablumyan - La Jolla CA
Dmitry Berger - San Diego CA
John N. Hait - San Diego CA
Bruce E. Smith - Santee CA
Assignee:
All Optical Networks, Inc. - San Diego CA
International Classification:
G02F 111
US Classification:
359279, 359285, 359305, 359246, 359238
Abstract:
Multi-domain, phase-compensated, differential-coherence detection of photonic signals for interferometric processes and devices may be manufactured holographically and developed in situ or with an automatic registration between holograms and photonic sources in a single frame. Photonic or electronic post processing may include outputs from a cycling or rotation between differently phased complementary outputs of constructive and destructive interference. A hyper-selective, direct-conversion, expanded-bandpass filter may rely on an expanded bandpass for ease of filtering, with no dead zones for zero beat frequency cases. A hyper-heterodyning, expanded bandpass system may also provide improved filtering and signal-to-noise ratios. An ultra-high-resolution, broadband spectrum analyzer may operate in multiple domains, including complex “fingerprints” of phase, frequency, and other parameters. The associated technologies of the invention may be used to produce extreme precision in multi-domain locking of sophisticated waveforms varying in several domains.

Photonic Channel Allocator And Shifter

US Patent:
2002013, Sep 19, 2002
Filed:
Mar 16, 2001
Appl. No.:
09/810884
Inventors:
Bruce Smith - Santee CA, US
Michael Myers - San Diego CA, US
Clark Guest - San Diego CA, US
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.
