Abstract: The inventive opto-electronic switch comprises a light-emitting element (1) and a receiving element (2) which outputs a first signal (U(t)) whose value changes according to the amount of light received. The emitting element (1) and the receiving element (2) are arranged in such a manner that the light emitted by the emitting element (1) is diffused or reflected by objects, which are located within a determined area, such that at least one portion of this diffused or reflected light reaches the receiving element (2). The first signal (U(t)) is fed to an evaluation unit in which a switching element (18) changes its switching state if the change of the amount of reflected or dispersed light received by the receiving element, which is caused by motion of the object, is located within the limits of a predetermined motion pattern that corresponds to a tapping of a defined area. The evaluation unit determines time-variable changes in motion and identifies a change in motion of the object as tapping.

Abstract: A surface having specular regions shaped to reflect incident light toward an optical sensor provides an ideal surface to be scanned by an optical mouse. When light is shined upon the surface, the reflections off of the specular regions appear as white points in the image acquired by the optical sensor, which gives the optical sensor the distinguishing characteristics it needs to differentiate between images. Since the specular regions reflect light so well, less light is needed to obtain an image, and power is conserved. The surface appears as a dark background in the image, providing contrast to the light reflecting off the specular regions. To protect the specular regions, an optically transparent coating can be layered on top of the surface. An alternative surface that may be easier to manufacture is a light colored surface dotted with darker colored regions.

Abstract: A method and apparatus for optical wavelength routing separates even and odd optical channels from an input WDM signal. The input beam is first converted to at least one pair of orthogonally-polarized beams. A split-mirror resonator has a front mirror with two regions having different reflectivities, and a reflective back mirror spaced a predetermined distance behind the front mirror. Each of the orthogonally-polarized beams is incident on a corresponding region of the front mirror of the split-mirror resonator. A portion of each beam is reflected by the front mirror, which the remainder of each beam enters the resonator cavity where it is reflected by the back mirror back through the front mirror. The group delay of each reflected beam is strongly dependent on wavelength. The two reflected beams from the resonator are combined and interfere in a birefringent element (e.g., a beam displacer or waveplates) to produce a beam having mixed polarization as a function of wavelength. The polarized components of this beam are separated by a polarization-dependent routing element (e.g., a polarized beamsplitter) to produce two output beams containing complimentary subsets of the input optical spectrum (e.g., even optical channels are routed to output port A and odd optical channels are routed to output port B).
