摘要： An optical device includes a waveguide including a first medium, which is transparent and has a first index of refraction at a target wavelength and which has mutually-parallel first and second surfaces arranged so that light at the target wavelength propagates within the waveguide by internal reflection between the first and second surfaces. A coupling layer is disposed over the first surface of the waveguide and includes a second medium having a second index of refraction at the target wavelength, which is greater than the first index of refraction, and is patterned to define a periodic array of cylinders, which have respective cylinder axes perpendicular to the first surface and have respective heights and diameters that are smaller than the target wavelength, and which are spaced apart such that a distance between each of the cylinders and a neighboring cylinder in the array is less than the target wavelength.

摘要： A light guide assembly (2) for use in a touch sensitive area (3) of an optical touch sensing device (1) for touch screens is configured to receive light, to allow the light thereby received to propagate in the light guide assembly, and to deliver the light thereby propagated in the light guide assembly further out of the light guide assembly. The light guide assembly comprises a plurality of light guide stripes (4, 4′ 5) for controlling the light propagation, and an interaction arrangement (27; 17; 21) configured to define at least one restricted interaction area (11) within the touch sensitive area for interaction between the light and the external object. The optical touch sensing device is configured to detect the presence of an external object (10) on the basis of changes in the light delivered further out of the light guide assembly due to interaction of the light with the external object. According to the invention, the light guide assembly comprises source-to-detector lines (4, 4′, 5) for at least two sources (31) and detectors (41), the source-to-detector lines being formed by light guide stripes (4), each of which is divided into at least two substripes (4′), one for each detector, each source-to-detector line having one interaction arrangement (27) defining a restricted interaction area (11).

An efficient drive scheme is provided for matrix addressed arrays of IMods or other micromechanical devices. An improved color scheme provides greater flexibility. Electronic hardware can be field reconfigured to accommodate different display formats and/or application functions. An IMod's electromechanical behavior can be decoupled from its optical behavior. An improved actuation means is provided, some one of which may be hidden from view. An IMod or IMod array is fabricated and used in conjunction with a MEMS switch or switch array. An IMod can be used for optical switching and modulation. Some IMods incorporate 2-D and 3-D photonic structures. A variety of applications for the modulation of light are discussed. A MEMS manufacturing and packaging approach is provided based on a continuous web fed process. IMods can be used as test structures for the evaluation of residual stress in deposited materials.
