Patent number: 6643053Abstract: One embodiment of the present invention provides a spatial light phase modulator, which can perform piecewise linear phase modulation of a light beam. This spatial light phase modulator includes an array of movable micromirrors and an array of actuators. Each actuator of the array of actuators is movably coupled to one micromirror of the array of movable micromirrors and can move the micromirror both vertically and rotationally. Additionally, the present invention provides an optical function generator that is a femtosecond pulse shaper. This optical function generator includes a diffraction grating that disperses an input pulse into a dispersed spectrum, a lens assembly to focus the dispersed spectrum onto a micromirror array, and the micromirror array to provide spatial filtering to the dispersed spectrum to provide the filtered spectrum.Type: GrantFiled: February 20, 2002Date of Patent: November 4, 2003Assignee: The Regents of the University of CaliforniaInventors: Kebin Li, Jonathan P. Heritage, Kimberly T. Cornett, Olav Solgaard, Uma Krishnamoorthy

Patent number: 5166818Abstract: For use, e.g., in the compensation of frequency dispersion in the course of transmission of an optical signal, a pulse-shaping device is provided with a suitably shaped nonplanar mirror (16). When spatially spread-out frequency components--produced, e.g., by a grating (14)--are reflected from such mirror, a frequency-dependent phase shift is introduced; for example, such phase shift may be a third-order function of frequency. Upon recombination of frequencies, a shaped pulse is obtained. Furthermore, third-order compensation can be used to compress amplified light pulses, e.g. as produced by a semiconductor gain medium (80, 81).Type: GrantFiled: March 11, 1991Date of Patent: November 24, 1992Assignee: Bell Communications Research, Inc.Inventors: Eugene W. Chase, Peter J. Delfyett, Jr., Jonathan P. Heritage, Robert N. Thurston

Patent number: 4928316Abstract: A communications systems is characterized by a pulse-shaping technique for producing shaped, stabilized, ultra-short (picosecond to femtosecond) pulses containing encoded information. Pulse shaping is accomplished by temporally stretching and chirping an ultra-short pulse from a pulse generator, modulating the pulse in real time and temporally compressing the pulse in a manner so as to cancel the original chirp.Type: GrantFiled: February 4, 1988Date of Patent: May 22, 1990Assignee: Bell Communications Research, Inc.Inventors: Jonathan P.
