Interference-Based Dwdm Optical Interleaver Using Beam Splitting And Selective Phase Shifting And Re-Combining

View page
US Patent:
6741813, May 25, 2004
Filed:
Dec 20, 2000
Appl. No.:
09/742749
Inventors:
Zhenpeng Su - Fremont CA
Yi Qin - Pleasanton CA
Hongchuan Wang - Fremont CA
Assignee:
Nexfon Corporation - Fremont CA
International Classification:
H04J 1402
US Classification:
398 79, 398 86, 359496, 359497
Abstract:
An interleaver comprises a serial array of optical elements to which a multichannel, continuous spectrum, composite signal is input and two multichannel, non-continuous spectrum, composite signals are output. Two embodiments are disclosed. One such embodiment provides output composite signals which are spectrally symmetric in that each such non-continuous spectrum contains the same number of channels albeit of alternating center wavelengths. The other such embodiment provides output composite signals which are spectrally asymmetric in that each such non-continuous spectrum contains either a different number of channels or an equal number of channels of narrower or wider passband. Each of the preferred embodiments comprises an array of optical elements which split the input composite signal into components of different polarization states, selectively add phase shifts to some of these components and recombine them a number of times. The inventive arrays operate on the incident composite signal light beam to produce interference effects which attenuate the unwanted wavelength components in each composite output signal and reinforce the desired wavelength components.

Multi-Channel Wavelength Slicing Using An Etalon-Based Interleaver For Dense Wavelength Division Multiplexing

View page
US Patent:
20020003643, Jan 10, 2002
Filed:
Dec 16, 2000
Appl. No.:
09/738904
Inventors:
Charles Qian - Cupertino CA, US
Yi Qin - Pleasanton CA, US
Hongchuan Wang - Fremont CA, US
International Classification:
H04J014/02
US Classification:
359/127000, 359/124000
Abstract:
A versatile, wavelength-slicing device, referred to herein as an optical spectrum synthesizer (OSS), provides new avenues and technologies for optical communication applications. Specifically, OSS separates a composed optical signal into two output spectra. Each output spectrum carries a multiple of optical communication signal channels. The bandwidth of each channel and spacing between adjacent channels may differ from one output to the other. The cascades of OSS devices, the combinations of OSS with prior art components and modules, and other new devices to be used in conjunction with OSS lead to new Spectrum Devices that add new dimensions to existing and new optical network architectures. The invention of OSS leads to new Spectrum Wavelength Division Multiplexing and management devices based on cascades of OSS devices. Examples of these devices include Spectrum Multiplexer, Spectrum Demultiplexer and Spectrum Add Drop Module. The combinations of OSS and other prior art devices also lead to several new Spectrum devices and modules. Examples of these include, Spectrum Switch, Spectrum Cross-Connect and Spectrum Long Haul Transport Modules. Other devices designed to be used in conjunction with OSS, e.g., 1/n Multiplexer and 1/n Demultiplexer, can also be used to form new devices and modules.

Optical Fiber Collimator With Long Working Distance And Low Insertion Loss

View page
US Patent:
20020197020, Dec 26, 2002
Filed:
Jun 23, 2001
Appl. No.:
09/888702
Inventors:
Charles Qian - Cupertino CA, US
Yi Qin - Pleasanton CA, US
International Classification:
G02B006/36
G02B006/32
US Classification:
385/080000, 385/079000, 385/033000
Abstract:
A compact, low loss optical fiber collimator design consists of a lens, a glass wedge, and a single- or multi-fiber pigtail. The introduction of the glass wedge ensures minimum off-axis beam deflection and hence improves device reliability. By properly selecting the focusing lens, low insertion losses and long working distances in both reflection (for a multi-fiber collimator) and transmission are achieved. These collimators are critical to interferometer type devices and other micro-optical devices where uniform phase front and/or long path length are desired.

Spectrum Division Multiplexing For High Channel Count Optical Networks

View page
US Patent:
20030035168, Feb 20, 2003
Filed:
Mar 17, 2001
Appl. No.:
09/811136
Inventors:
Charles Qian - Cupertino CA, US
Yi Qin - Pleasanton CA, US
Hongchuan Wang - Fremont CA, US
International Classification:
H04J014/02
US Classification:
359/124000
Abstract:
A versatile, wavelength-slicing methodology, referred to herein as spectrum division multiplexing (SDM), provides new avenues and technologies for optical communication applications. Specifically, SDM separates a composed optical signal into a group of output spectra. Each output spectrum carries a multiple of optical communication signal channels. The bandwidth of each channel and spacing between adjacent channels may differ from one output spectrum to another. A critical building block of SDM technology is a spectrum filter with periodic passbands, referred to herein as an optical spectrum synthesizer (OSS). The cascade of OSS devices, the combinations of OSS with prior art components and modules, and other new devices to be used in conjunction with OSS, lead to new spectrum devices that add new dimensions to existing and new optical network architectures. The invention of OSS leads to new Spectrum Division Multiplexing and management devices based on cascading OSS devices. Examples of these devices include Spectrum Exchanger, Spectrum Multiplexer, Spectrum Demultiplexer and Spectrum Add Drop Module. The combinations of OSS and other prior art devices also lead to several new Spectrum devices and modules. Examples of these include, Spectrum Switch, Spectrum Cross-Connect and Spectrum Long Haul Transport Modules. Other devices designed to be used in conjunction with OSS, e.g., 1/n Multiplexer and 1/n Demultiplexer, can also be used to form new devices and modules. In SDM methodology, spectra (group of channels), instead of single channels, are managed collectively thereby offering both flexibility and efficiency for next generation high channel count optical networks.
