Publication number: 20020181038Abstract: A particular signal from a legacy photonic source may have a distribution of wavelengths in a particular signal that is excessively broad for modem, narrowband equipment. In order to provide a drop-in apparatus for integrating modem narrowband signal carrying and handling devices with legacy equipment as either sender or receiver, various implementations of a data stabilizer are provided. Data stabilizers may rely on information transfer mechanisms, signal directors, wavelength shifters, cross-gain modulation, cross-phase modulation, and four-wave mixers. Moreover, data stabilizers may be implemented directly as multiplexers, or integrated into systems using conventional multiplexers.Type: ApplicationFiled: June 1, 2001Publication date: December 5, 2002Inventors: John N. Hait, Arkady S. Bablumyan

Publication number: 20020131124Abstract: An apparatus for photonic wavelength shifting and stabilization is described. The apparatus 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 devices are supported. The modulation waveform is optimized for the particular modulation device. 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.Type: ApplicationFiled: March 16, 2001Publication date: September 19, 2002Inventors: Michael H. Myers, Juan C. Riley, Charles D. Melville, Arkady S. Bablumyan, Clark C. Guest

Publication number: 20020085205Abstract: 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.Type: ApplicationFiled: December 27, 2000Publication date: July 4, 2002Inventors: Arkady S. Bablumyan, John N. Hait
