摘要： This invention relates to reconfigurable spatial light modulators (SLM) incorporating a scatter plate. Computer generated diffraction patterns or holograms may be loaded on the (SLM) either as a single frame or as a series of frames for observation by an observer. In a preferred embodiment both an electrically addressable spatial light modulator (EASLM) and an optically addressable spatial light modulator (OASLM) are used. The (OASLM) may be formed of several smaller (OASLMs) arranged in a matrix format. The faster (EASLM) forms a light pattern on sub-areas of the large (OASLM) in turn to give a large display. The scatter plate is arranged at the output of the (SLM) nearest an observer. This scatter plate has a known characteristic and serves to increase the field of view and/or reduce the number of pixels required to give a holographic or two dimensional displays. Prior to producing a display, the diffraction patterns, holograms, or image in the computer is modified to take account of the properties of the scatter plate; a modified computer generated diffraction pattern, hologram, or image is then displayed to an observer. The system may also be used for optical switching.

摘要： A semiconductor optical device, which includes a semiconductor substrate, an electro-absorption modulator, and at least one optical device is monolithically integrated on the semiconductor substrate. An insulative layer surrounds the electro-absorption modulator and the optical devices on the semiconductor substrate, at least two metallic pads, one of which being an electrode of the modulator, are formed at a distance from each other on the insulative layer. A plurality of metallic wires are adapted for electrically connecting the electro-absorption modulator to the metallic pads and adjusting a value of inductance of the electro-absorption modulator. The metallic wires are formed on the insulative layer. A dielectric layer formed under the insulative layer provides a minimizing of parasitic capacitance generated in the metallic pads and the metallic wires by being formed under the metallic pads and the metallic wires.
