摘要： The specification describes techniques for cleaving crystal bodies, e.g. semiconductor laser bars, using thermostatic cleaving tools. Use of such tools allows the cleaving process to occur in an ultra high vacuum chamber without the use of mechanical devices activated from the exterior of the chamber. Cleaving occurs automatically and controllably by locally heating the cleaving tools, thereby deflecting the thermostatic element against the laser bar and causing fracture.

摘要： A long wavelength (6 to 20 .mu.m) phototransistor is described which has n-doped silicon as emitter and collector regions bracketing a base region having a quantum well structure made up of alternating layers of p-doped silicon germanium and undoped silicon, The silicon germanium layer adjacent to the emitter region is thicker and has a higher percentage of germanium in order to provide a quantum well that is wider and deeper than the other quantum wells in the base region thereby resulting in a larger current and optical gain. The silicon barrier layer of the quantum well closest to the collector region is p-doped in order to reduce the leakage current of the base-collector junction.

摘要： A communication network includes a local area network (LAN) and a wireless access point coupled to the LAN. In one embodiment, each access point includes a medium access control (MAC) stage, and a radio frequency (RF) transmitter/receiver for communicating unsecure message data via RF links with users of associated wireless devices. An optical transmitter/receiver in the access point enables the users to communicate secure message data over the LAN via free space optical (FSO) links with the users. The MAC stage operates (i) to direct unsecure data from the LAN to the wireless device users and to direct unsecure data from the users to the LAN, via the RF transmitter/receiver; and (ii) to direct secure data from the LAN to the wireless device users and to direct secure data from the users to the LAN, via the optical transmitter/receiver. An integrated VoIP/FSO portable handset is also disclosed.

摘要： Methods, systems and other embodiments associated with a laser communication system using a single wavelength are presented. A first data is modulated onto an RF carrier to produce a modulated RF carrier. A laser is intensity modulated using with the modulated RF carrier. The intensity modulated laser beam is transmitted from an interrogator to a modulating retro-reflector (MRR) terminal. A portion of the laser beam is received at a receiver at the MRR terminal. Another portion of the laser is modulated at the MRR terminal with a second data to produce a re-modulated laser beam. The re-modulated laser beam is reflected back to the interrogator.

摘要： A fiber optic link for platforms with data sources including, e.g., sensors, cameras, radars and antennas. An array of optical transmitter/receiver pairs is coupled to an integrating network of the platform. Data modules are each coupled to certain ones of the data sources and include a receiver for detecting control data, and a modulator for modulating a light signal according to signals from the module's data sources. At least one optical fiber is coupled between a given transmitter/receiver pair of the array, and a corresponding data module. A laser source associated with each transmitter supplies a light signal with the control data to a corresponding data module downstream over an optical fiber. The light signal is modulated by the signals from the module's data sources, and the modulated light signal is returned to an array receiver upstream over an optical fiber.
