Abstract:

A spread polarization transmitter for transmitting at least one light signal comprises a spread-spectrum communication apparatus and a polarization modulator. The spread-spectrum communication apparatus modulates the at least one light signal according to a spread-spectrum modulation technique. The polarization modulator comprises a polarizer and a magnetic bubble waveguide. The polarizer is capable of polarizing the at least one spread-spectrum modulated light signal in a polarized direction. And the magnetic bubble waveguide, which is configured in accordance with a pseudo-random polarization code sequence such that the plurality of magnetic bubble domains assume a time varying position representative of the pseudo-random polarization code sequence, is capable of receiving at least one polarized, spread-spectrum modulated light signal. Thereafter, the magnetic bubble waveguide is capable of at least partially rotating the polarized, spread-spectrum modulated light signals by a predetermined angle from the polarized direction during transmission therethrough to create spread polarization modulated light signals.

US Classification:

372 26, 372290011

Abstract:

A diode laser for providing a high-energy coherent light beam suitably includes an array of laser diodes, each producing a laser beamlet. The beamlets are provided to a spatial light modulator (SLM) with an array of pixels, each pixel corresponding to a portion of the light beam. The phase variation across the light beam wavefront is monitored at a detector, and a feedback signal indicative of the phase variation is provided to control electronics. The control electronics process the feedback signal to modulate a local index of refraction within one or more pixels of the SLM to reduce the variation in phase across the beam wavefront. Because phase variations across the beam wavefront are reduced, relatively large diode arrays can be formulated, thereby resulting in relatively high powered diode lasers.

US Classification:

345 30, 345 86, 385 1, 385 4, 385 6

Abstract:

Systems and methods are disclosed for providing a more robust flat panel display by using the Faraday effect to control light emission from a solid state material so as to form two-dimensional or three-dimensional images. Flux tubes can be configured to define a two dimensional array. Each flux tube is somewhat analogous to a single bubble of a magnetic bubble memory and can define a pixel. At least some aspect of light transmitted through a flux tube can be varied thereby, so as to facilitate the formation of an image.

US Classification:

398105, 398116, 398117

Abstract:

Described herein are embodiments of displays which may be used in high pressure environments, e. g. , in underwater environments, and systems which utilize such displays. In some embodiments, a system comprises at least one electronic device comprising an optical output, a first optical interface to couple the optical output to an optical transmission medium, a second optical interface coupled to the optical transmission medium, and a display coupled to the second optical interface. In some embodiments the second optical interface comprises a material having a graded index of refraction, and the display comprises an optically transmissive material coupled to the second optical interface to transmit an image from the second optical interface to a reflective surface.
