An optical device including dynamic channel equalization is provided. In an exemplary multiplexer or line amplifier configuration the device includes a plurality of separate optical paths, each of which receiving a separate group of optical signals. Each group of optical signals is provi
6760532 Optical device having dynamic channel equalization July 6, 2004
An optical device including dynamic channel equalization is provided. In an exemplary multiplexer or line amplifier configuration the device includes a plurality of separate optical paths, each of which receiving a separate group of optical signals. Each group of optical signals is provi
6337933 Narrow bandwidth fiber bragg grating apparatus January 8, 2002
In accordance with the present invention, an optical device is provided which selects narrowly spaced optical channels used in dense wavelength division multiplexed systems. The device includes a first and second Bragg gratings in a cascaded configuration where each grating has a length
6233080 Crosstalk-free signal source for dense wavelength division multiplexed systems May 15, 2001
An optical device is provided which locks the wavelength output of a laser transmitter in an optical transmission system as well as preventing the propagation of unwanted signals generated by the laser transmitter prior to the transmitter reaching the desired operating wavelength thereby
6115403 Directly modulated semiconductor laser having reduced chirp September 5, 2000
In accordance with the present invention, an in-line fiber Bragg grating is coupled to the output of a directly modulated DFB laser. The grating preferably rejects chirp induced frequencies of light emitted by the DFB laser. Accordingly, light transmitted through the grating is spectrall
6097865 Design and method for planar coupled waveguide filter August 1, 2000
A wavelength filter has a low index waveguide, a high index waveguide and a grating for coupling therebetween. The high index waveguide is in horizontal proximity to said low index waveguide. The low index waveguide and said high index waveguide have substantially different geometries
6088493 Fiber shuffle interconnection apparatus and method July 11, 2000
An apparatus and method is provided for optical cross connections. A guide structure is used to guide optical fiber fed to various stations on the guide structure which correspond to input and output ports of a fiber shuffle interconnect. Once the fiber has been positioned about the guid
