Patent Number Title Of Patent Date Issued
6625354 Fiber amplifier having a prism for efficient coupling of pump energy September 23, 2003
An optical fiber amplifier employing a prism to optimally couple pump energy into the pump core of a dual clad fiber. The optical fiber amplifier consists of a dual clad fiber having an inner (e.g., signal) core, an outer (e.g., pump) core surrounding the inner core, and a cladding l
6597836 Optical phased array control system July 22, 2003
A real-time control system for an optical phased array is disclosed that comprises a computationally efficient algorithm for calculating phase differences between a plurality of array beamlets and a reference plane wave and further generates phase correction signals that are transmitted
5847817 Method for extending range and sensitivity of a fiber optic micro-doppler ladar system and appar December 8, 1998
A method for compensating a reference signal used in a coherent receiver of a micro-doppler sensor having a transmitter includes the steps for: (a) repeatedly measuring phase differences between a signal emitted by the transmitter a first time and a previous signal emitted at a previous
5832163 Single mode optical waveguide with expanded rare-earth doped region November 3, 1998
A single mode optical waveguide includes a first region having a relatively high refractive index, a second region having a relatively low refractive index disposed adjacent to the first region, and a dopant region overlapping the first and second regions. Preferably, the first and secon
