摘要： The present invention relates to an optical switch which will generate and emit a beam of light when an optical signal is directed therein, but includes means to inhibit the generation of the beam of light when a second optical signal is directed therein. The switch includes a light emitter formed of a plurality of layers of alternating opposite conductivity type which is adapted to generate the beam of light when an optical signal is directed therein. A photovoltaic inhibitor is connected to the emitter so that any current generated by the inhibitor is applied across the emitter in a manner to prevent the generation of the light in the emitter. The photovoltaic inhibitor generates the current when a second optical signal is directed therein. Depending on the external circuit, the device can be operated in either a digital (bistable) or analog mode.

摘要： A number of light sensitive/generating devices are arranged in rows and columns to thereby form an X-Y pixel matrix. All devices are interconnected to a source of operating voltage such that the first device to turn on, i.e., the first device to receive an actuating intensity of light is actuated to thereafter emit light. The current flow through this one activated device causes a voltage drop that prevents any other light sensitive/generating device from turning on. In this way, the pixel that receives the maximum light intensity is identified by its position in the X-Y matrix. Both optical and electrical means are provided to locate the X-Y matrix position of the activated light sensitive/generating device. In an optical embodiment, two orthogonal cylindrical lenses are placed in front of two linear CCDs in order to find the X-Y coordinates of the active light sensitive/generating device. In an electrical embodiment, the X-Y coordinates of the active light sensitive/generating device is electrical read out by reading the current through row/column resistors that are associated with the active light sensitive/generating device. The use of a saw tooth source of operating voltage enables determination of the illumination intensity of the maximum light intensity pixel.

摘要： Dynamic variation in the color produced by a silicon quantum dot laser is achieved by utilizing segmented sections or patches of quantum dots of differing sizes to produce different colors of light. The amount of each color of light produced is controlled by selectively biasing the segments of quantum dots. The light is caused to resonate coherently and is emitted out by a diffraction grating. The dynamic variation in the color of light produced by such a device makes it useful as a multicolor pixel in a color display of images.

摘要： A novel hydrogen rich single crystal silicon material having a band gap energy greater than 1.1 eV can be fabricated by forming an amorphous region of graded crystallinity in a body of single crystalline silicon and thereafter contacting the region with atomic hydrogen followed by pulsed laser annealing at a sufficient power and for a sufficient duration to recrystallize the region into single crystal silicon without out-gassing the hydrogen.

摘要： In a semiconductor device, a thin, synthetic diamond film (i.e. a man made film) enhances the transfer of heat from a semiconductor circuit chip to a cooling medium. The heat generating semiconductor circuit chip is located in efficient thermal transfer engagement with one surface of a synthetically deposited diamond film. The opposite surface of the diamond film forms the bottom wall of a cavity that contains a cooling medium. In one embodiment of the invention, the cavity is formed by depositing the diamond film on the surface of a silicon substrate, and then etching the silicon substrate to form an open-top cavity having side walls that comprise the silicon substrate, and having a bottom wall that comprises the diamond film. In a second embodiment of the invention, the open-top cavity is formed by an apertured silicon preform that is bonded to the diamond film. A capping member closes the top of the cavity. A cooling medium is placed within the cavity a fluid cooling medium may be circulated. through the cavity by the use of an inlet and an outlet that are located in the capping member.

摘要： An optical switching array includes a body of a semiconductor material having opposed surfaces. A plurality of spaced bodies of a semiconductor material are on one of the surfaces of the substrate. Each body includes four superimposed regions extending thereacross with the regions being of alternating opposite conductivity type to form PN junctions between adjacent regions. The bodies are capable of emitting light in response to an optical input when an electrical bias is applied thereacross. A fifth region extends across each body and forms a Zener diode with one of the outer region of the body. The Zener diode is adapted to limit the voltage drop across the bodies when one of the bodies is biased to emit light so as to permit more than one body to be turned to its light emitting condition at any one time.

摘要： An optoelectronic device having an optical switch which can be turned on and off optically by a beam of light. The device includes the optical switch having a first optically variable resistance device connected in series with the switch and one side of a source of current, and a second optically variable resist device connected in series with the switch and one side of a source of current, and a second optically variable resistance device connected in series with the switch and the other side of the current source. The switch is capable of emitting light when a voltage above a threshold is applied thereto. By directing a light into the first optically variable resistance device the voltage applied across the switch is increased to a level just below the threshold and is raised to at least the threshold by directing a light into the switch so as to turn on the switch. The switch is turned off by directing a beam of light into the second optically variable resistance device which reduces the voltage applied across the switch below a holding voltage.
