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).

Subclass 123: OPTICAL FIBER WAVEGUIDE WITH CLADDING
Subclass 125: Utilizing nonsolid core or cladding
Subclass 131: Multilayer structure (mixture)
Subclass 27: Particular coupling function
Subclass 30: Evanescent wave coupling
Subclass 39: Particular coupling structure
Subclass 41: Directional coupler
Subclass 42: Directional coupler
Subclass 49: Fiber to thin film devices
Subclass 88: Optical fiber to a nonfiber optical device connector
Subclass 89: Plural fiber/device connections
Subclass 90: Fiber adjustable relative to device
Subclass 91: Fiber permanently fixed after adjustment

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.

Subclass 1: FAULT RECOVERY
Subclass 143: Multimode
Subclass 182: TRANSMITTER
Subclass 59: Ring or loop
Subclass 85: Filter
Subclass 89: Multiple Access (e.g., WDMA)
