摘要： This invention relates to devices for coupling light between an optical waveguide and an optical element in a manner that is substantially independent of temperature, using reflective optics. Certain embodiments of the invention concern improved designs for the transmit and receive optics of a waveguide-based optical touch screen sensor, incorporating reflective optics. The improved designs have substantially temperature independent operation and reduced optical losses. In one preferred embodiment the improved design incorporates a parabolic or quasi-parabolic reflector. In another preferred embodiment the improved design incorporates an elliptical or quasi-elliptical reflector. The transmit and receive elements and associated waveguides preferably comprise photo-patternable polymers.

摘要： Planar lenses for integrated optics applications, in particular for use in optical touch screen sensors are disclosed. The disclosed planar lenses include a slab waveguide and an optical waveguide, preferably formed in unitary fashion, wherein the slab waveguide has a curved end face to focus light into or out of the optical waveguide, and wherein at least one additional lens is included within the slab waveguide. In one aspect of this disclosure, the additional lens is a diverging lens. In a second aspect the additional lens is a converging lens. The additional lens may match the acceptance angle of the optical waveguide to the curved end face of the slab waveguide. Alternatively, it may improve the tolerance of the planar lens to design or assembly errors and/or temperature variations. Preferably, the planar lenses are composed of a photo-patternable polymer, and the additional lenses are composed of air.

摘要： This invention relates to optical splitters, particularly to optical splitters for use in optical touch screens. The present invention provides an optical splitter for distributing light substantially equally from a multimode input waveguide to an array of output waveguides, via a slab region. The distribution of output waveguide widths is chosen to complement the intensity distribution in the slab region, which may or may not be substantially uniform. The invention also provides an optical splitter for distributing light substantially equally from an optical source to a plurality of waveguides, wherein said optical source directs a beam of light into a slab region. The distribution of waveguide widths is chosen to complement the intensity distribution in the slab region, which may or may not be substantially uniform. When used to distribute optical power in optical touch screens, the splitters of the present invention may be used in series and/or in parallel.
