Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 385: Optical Waveguides

(1) An optical waveguiding element, which conveys light from one point to another through an optically transparent elongated structure by modal transmission, total internal reflection, or total reflectorization. (2) A combination of an optical waveguiding element with an additional broadly recited optical element which couples light or a combination. (3) A combination of an optical waveguiding element with structure which mechanically joins this waveguiding element with another or with a diverse optical element. (4) An optical modulator where the modulation of a light wave characteristic is performed exclusively within an optical waveguiding element. (5) Other miscellaneous devices formed of an optical waveguide (e.g., a waveguide sensing device) and supplemental devices which are limited to use with an optical waveguide (e.g., an external clamp or retainer).

Class 398: Optical Communications

This class provides for all types of communication systems in which optical signals are used to transmit modulated carrier wave information between points. Such communication includes transmitting an intelligence-bearing signal from one point to another in the form of variations in a characteristic of the light wave. The communication may be through free space, fibers or waveguides. These are used to transfer the information with an optical beam, and this beam can be used in various communication schemes to enable the most effective or desired method of moving the information, including optical multiplexing when plural information signals or plural transmitters and receivers are utilized.
