摘要： A method and apparatus for growing a single crystal Kb2Cl5 material in a growth furnace comprising an upper zone set at 480° C. A single crystal Kb2Cl5 material is grown from a single Kb2Cl5 grain until a eutectic point is reached. The upper zone is cooled at 1°/hour to 380° C. The single crystal Kb2Cl5 material is annealed. The single crystal Kb2Cl5 material is cooled at 10°/hour to room temperature. Optionally, the method further includes loading an ampoule with Kb2Cl5 powder, the ampoule including a plug, which includes a seeding well and an aperture. The Kb2Cl5 powder is melted, thereby generating a melt. The melt is frozen to capture a polycrystalline Kb2Cl5 material in the seeding well, thereby generating a polycrystalline Kb2Cl5 seed. The ampoule is loaded into the growth furnace. The polycrystalline Kb2Cl5 material is melted except for the polycrystalline Kb2Cl5 seed, the polycrystalline Kb2Cl5 seed including the single Kb2Cl5 grain. The polycrystalline Kb2Cl5 material is grown until the single Kb2Cl5 grain is isolated by the aperture.

摘要： A multiple quantum well spatial light modulator combines both optically addressed and electrically addressed portions on a single wafer. The electrically and optically addressed portions may be physically distinct or combined. To fabricate the modulator, a portion of an optically addressed multiple quantum well spatial light modulator is configured as an electrically addressed portion by pixellating that portion of the multiple quantum well wafer. The frequency of the applied voltage to the electrically addressed portion is increased such that the voltage switches faster than both the dark and illuminated screening time. The electrically and optically addressed portions may be combined or positioned side-by-side. The spatial light modulator has applications in a wide variety of low-cost, high performance pattern recognition systems. In one system, a first infrared beam impinges the electrically addressed portion of the modulator and picks up the pattern electrically written thereon (i.e., the template image). A second infrared beam impinges the optically addressed portion of the modulator and picks up the pattern written thereon by a white light writing beam (i.e., sample image). The first and second infrared beams then pass through a lens, where the beams are Fourier transformed in the plane of an optically addressed spatial light modulator (OASLM). The correlation hologram formed on the OASLM is read out by a third infrared beam and detected using a photodiode array. In a second system, the lens and OASLM are replaced with a parabolic reflector which reflects the first and second infrared beams onto the optically addressed portion of the modulator.

摘要： A system for remote optical communications includes a base station and a remote station. The remote station includes a retroreflector, a multiple quantum well modulator (MQW), and drive circuitry that drives the MQW. A base station transmitter sends an interrogating light beam to the MQW, which modulates the light beam based on the information in the electrical signal from the drive circuitry. The retroreflector reflects the modulated light beam to the base station for detection by a receiver.
