Firm develops superconductor chips for PCs
Article Abstract:
Conductus Inc says it has developed a data-storage chip that is at least 10 times faster than the fastest chips currently used in computers. The 32-bit memory chip marks a major milestone in efforts to bring superconducting to electronics. Superconducting devices may find some commercial uses in digital communications and other specialized applications by the mid-1990s, and there may eventually be general-purpose superconducting integrated circuits. Tests showed that the experimental chip's internal clock operates at 120 billion cycles per second, or 2,000 to 3,000 times faster than the clocks of today's high-end personal computers. AT and T Bell Laboratories and Sandia National Laboratories collaborated with Conductus, which is partly funded by Hewlett-Packard Co, on the research project.

Scientists find silicon emits laser's light
Article Abstract:
Findings about a light-emitting form of silicon, originally reported by British scientists in Applied Physics Letters in 1990, are confirmed by researchers working at AT&T's Bell Labs. The discovery involves a way to cause silicon that has been subjected to an acid-etching process to emit light. If green light from a laser is shone onto such processed, 'porous' silicon, red light is emitted. The discovery, which might be an important step on the way to development of data-processing technologies based on light, has caused the Materials Research Society to schedule a special session at the society's general meeting in Anaheim, CA. A spokesman for AT&T cautions that many obstacles remain to be overcome before silicon-based optical devices are developed.

Research sheds light on silicon for use in superfast transmissions
Article Abstract:
Silicon researchers indicate that they have been successful in electronically inducing silicon to emit light. Industry observers note that the technological advance has substantial significance to the future of optoelectronic technology, which involves the use of light instead of electricity to carry information. Porous silicon has already been shown to glow when a laser was shone on it, but it will take electric stimulation to effectively couple electronic and optical devices. Light-transmitted information travels much faster than electrically transmitted information and has much potential use in computer technology.
