Patent for Sale:

Optical Device Portfolio    

Can be used to achieve an alignment in optical devices and LD's.

The patent portfolio offers an integrated device that includes a cantilever and a light source e.g. LED, LD or SEL incorporated together on a single substrate. The technology can be used to achieve an alignment in optical devices and LD's. The portfolio also covers an optical coupler sensor that uses both a fixed and movable optical waveguide to detect very small physical quantities, it is highly sensitive. The patent provides a method to manufacture such devices.

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 257: Active Solid-State Devices (E.G., Transistors, Solid-State Diodes)

This class provides for active solid-state electronic devices, that is, electronic devices or components that are made up primarily of solid materials, usually semiconductors, which operate by the movement of charge carriers - electrons or holes - which undergo energy level changes within the material and can modify an input voltage to achieve rectification, amplification, or switching action, and are not classified elsewhere.

Subclass 414: RESPONSIVE TO NON-ELECTRICAL SIGNAL (E.G., CHEMICAL, STRESS, LIGHT, OR MAGNETIC FIELD SENSORS)

Class 850:

Class 977: Nanotechnology

This art collection provides for disclosures related to: nanostructure and chemical compositions of nanostructure; device that include at least one nanostructure; mathematical algorithms, e.g., computer software, etc., specifically adapted for modeling configurations or properties of nanostructure; methods or apparatus for making, detecting, analyzing, or treating nanostructure; and specified particular uses of nanostructure. the term "nanostructure" is defined to mean an atomic, molecular, or macromolecular structure that: has at least one physical dimension of approximately 1-100 nanometers; and possesses a special property, provides a special function, or produces a special effect that is uniquely attributable to the structure s nanoscale physical size.

Subclass 870: Optical lever arm for reflecting light
