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 24: Plural (e.g., data bus)
Subclass 33: Lens
Subclass 49: Fiber to thin film devices
Subclass 52: With alignment device
Subclass 88: Optical fiber to a nonfiber optical device connector
Subclass 92: With housing
Subclass 93: Including lens

Class 264: Plastic And Nonmetallic Article Shaping Or Treating: Processes

Processes for molding, casting, or shaping of nonmetallic materials to produce articles. Liquid or melt comminuting of materials other than glass or metal. Uniting or compacting of bulk or randomly assembled particles. Furnace Lining or repair. Melt shaping in the absence of a mold or shaping surface, e.g., spheroidizing of particles. Working or treatment of nonmetallic materials not otherwise provided for.

Subclass 1.24: Optical fiber, waveguide, or preform
Subclass 1.26: Having lens integral with fiber

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 68: WDM
Subclass 84: Grating
