It is pointed out that passive and electroactive organic optical materials open new possibilities for fabricating enhanced and novel photonic devices. Low deposition temperatures and benign chemistry permit multiple-layer structures and integration of the organic materials directly with semiconductor electronics. The electrooptical properties of the active organics are comparable to or larger than conventional semiconductor and crystalline ceramic materials, and allow replacement of these materials with the electrooptical organics. The fabrication and optical characteristics of optical organics make possible the formation of monolithic packages applicable to control of signals in computational and communication systems. Photonic multichip modules, hybrid optical/electronic nonlinear systems, and phased-array optics are technologies that can be realized more effectively with organic photonics.<>

The authors consider the performance of an optical communication system where an unmodulated reference signal is transmitted along with the information-carrying signal to alleviate the effect of phase noise. When the power of the two signals and the receiver bandwidths are optimized, the resulting performance is significantly better than that of traditional amplitude and frequency modulation schemes. This makes reference transmission with a joint optimization of signal and receiver parameters a promising scheme for coherent optical communications.<>

The Autonomous Data Optical Relay Experiment (ADORE) was held at the Sea Test Range of the Pacific Missile Test Center off the coast of Southern California near San Nicolas Island during May 22-24 and May 28, 1991. The optical communication system operated with a green downlink based on a diode-pumped frequency-doubled Nd:YAG transmitter communicating with a quartz birefringent filter receiver and a blue uplink using an alexandrite laser wavelength shifted to the 455-nm doublet of cesium vapor sending information to a cesium filter receiver. Major achievements of the test included: first duplex laser communication with a submerged submarine; uplink initiated duplex laser communication from a submarine; demonstration of technologies which offer substantially higher performance at lower cost and risk compared with earlier efforts; extending the range and utility of laser communication by error correction coding and pulse summing; and establishing and experimental baseline for developing and investigating covert laser communication with submarine.<>

The author presents a practical hierarchical control system for telerobotic land vehicles. The goal of the architecture is to enable the user to have a relatively inexpensive control system that can be easily upgraded as the application demands. This is accomplished by having low-level modules that provide interfaces to hardware and the external environment and communicate with higher levels through the global memory. The levels of the hierarchy above the first level, referred to as layers of intelligence, are application dependent and allow the vehicle to execute more autonomous operation as the layers are added. There remains an operator interface to all levels of the hierarchy so that previous capabilities may be demonstrated while adding new levels. This architecture was implemented on RAYBOT, a robotic land vehicle at Sandia National Laboratories. The vehicle control module and the first layer of intelligence (teleoperation) have been implemented in hardware and have performed well. The ability to make quick modifications to the control system and the advantages of the hierarchical architecture have been demonstrated.<>

It is noted that the Advanced Communications Technology Satellite (ACTS) provides a glimpse of some of the communication technologies that can be utilized to meet the military's emerging communication needs. ACTS represents the beginning of the continuum that will see the military capitalizing on and making use of advances in commercial communications services. The imminent need is for a satellite system that provides variable data rates for personal communication to higher data rates and in a small terminal size. These requirements need to be provided as a commercial service and will have to meet the growing volume of military data communications requirements.<>

It is asserted that multichip modules (MCMs) provide a solution to the requirement for cost-effective high-performance packaging in the 1990s, and insight into the selection of an optimum interconnect technology is provided. The different types of interconnect substrates for MCMs are discussed, and it is argued that cofired ceramic and thin-film interconnect substrates are the most suitable ones for use in applications requiring high interconnect density. The issues associated with packaging MCMs are also discussed in detail, with emphasis placed on current implementations. Finally, an application of thin-film MCM technology being produced by nCHIP is reviewed.<>
