Patent Number Title Of Patent Date Issued
7123795 Methods for the alignment and calibration of the spectral responses of optical filters October 17, 2006
A method for aligning the spectral responses of two comb-like optical filters is provided. This method does not necessitate the use of spectrally-resolved equipment, as it uses the optical power correlation profile of a broadband light signal representative of the combined spectral r
6937793 Tunable chromatic dispersion compensator August 30, 2005
A tunable dispersion compensator for the compensation of the chromatic dispersion experienced by a single-channel or multi-channel light signal. The compensator includes a plurality of optical structures such as chirped Bragg gratings or combinations thereof, each having a characteristic
6842567 Power efficient assemblies for applying a temperature gradient to a refractive index grating January 11, 2005
The present invention discloses practical and power efficient assemblies for applying a temperature gradient to a fiber Bragg grating. An application of such assemblies is, for example, the active tuning of the chromatic dispersion of the grating. The temperature gradient is produced
5255283 Process for making a custom phase-conjugated circular mirror to be used in a laser resonator tha October 19, 1993
A process for making a custom phase-conjugated circular mirror to be used in a laser resonator that will suit specifications of a user is provided. The mirror reverses wavefront of one particular input beam .PSI..sub.o (x) determined by the user, the input beam .PSI..sub.o (x) having a g
