Appl. No.:

11/818883

Inventors:

William Benjamin Dress - Camas WA, US
Frederick Norman Magee - Loon Lake WA, US

Assignee:

Lightfleet Corporation - Vancouver WA

International Classification:

H04B 10/10

US Classification:

398 66, 398118, 398 82, 398164

Abstract:

Methods and apparatus are described for distribution optical elements and compound collector lenses for a broadcast interconnect. An apparatus includes a broadcast optical interconnect including: a plurality of nodes positioned to define a node array, each of the plurality of nodes having at least one optical signal emitter and a plurality of optical signal receivers positioned to define a receiver array that substantially corresponds to the node array; and a plurality of optics optically coupled to the array of nodes, the plurality of optics positioned to define an optics array that substantially corresponds to the node array and the receiver array, each of the plurality of optics including at least one optical distributing element and an optical collecting element, wherein an optical signal from the optical signal emitter is fanned-out by the at least one optical distributing element of one of the optics and broadcast to one of the plurality of receivers of all of the plurality of nodes by the optical collecting element of all of the plurality of optics.

International Classification:

G01R 29/08

US Classification:

702190, 702189

Abstract:

A coherent wideband acousto-optic RF spectrum analyzer for processing an input RF signal, having a CW laser providing a first laser beam, a Bragg cell used in a deflection mode with the laser beam incident thereon and receiving the input RF signal, and in response thereto producing multiple diffracted modulated light beams, a Fourier Transform lens with the modulated light beams incident thereon and in response thereto producing optical signal beams producing a Fourier Transform image in an image plane spaced apart from the Fourier Transform lens, and a photosensitive, optically re-writable medium positioned in the image plane with the optical signal beams incident thereon, the medium having an optical distribution pattern to function as a mask to attenuate a selected portion of the RF spectrum of the optical signal beams and produce an attenuated optical beam.

International Classification:

H04B 10/2575

US Classification:

Abstract:

An optical communications system is disclosed. In the optical communications system, a received light source is modulated in accordance with an electrical signal using an acousto-optic modulator. The acousto-optic modulator modulates an amplitude of the received light source in accordance with an amplitude of the electrical signal. Furthermore, an angle of diffraction of a beam produced by the acousto-optic modulator is a function of a frequency of the electrical signal. The optical communications system is equipped with a waveplate that converts a polarization of the diffracted beam to correspond to the polarization of an undiffracted beam. Improved detection and recovery of the electrical signal may be achieved due to the polarization correspondence between the diffracted beam and the undiffracted beam.
