Patent for Sale:Rare Earth Doped Polymeric Waveguide Amplifiers
Unlike conventional lithography followed by etching process, the invented direct writing/printing technique provides alternative for devices mass production and can greatly reduce their fabrication cost due to the reduced processing steps and the fabrication error.
Primary Application of the Technology
Class 359: Optical: Systems And Elements
Optical elements included in this class are: Lenses; Polarizers; Diffraction gratings; Prisms; Reflectors; Filters; Projection screens; Optical Modulators; Optical Demodulators. Among the optical systems included in this class are: Compound lens systems; Light reflecting signalling systems (e.g., retroreflectors); stereoscopic systems; Binocular devices; Systems of lenticular elements; Systems involving light interference; Glare reducing systems; Light dividing and combining systems; Light control systems (e.g., light valves); building illumination with natural light; Systems for protecting or shielding elements; Optical systems whose operation depends upon polarizing, diffracting, dispersing, reflecting, or refracting light; kaleidoscopes. Further included are certain apertures, closures, and viewing devices of a specialized nature which involve no intentional reflection, refraction, or filtering of light rays. This class also includes optical elements combined with another type of structure(s) to constitute an optical element combined with a nonoptical structure or a perfection or improvement in the optical element.Subclass 342: Particular active medium (e.g., crystal, plasma, fluid, etc.)
