Impacts of optoelectronics technology on ULSI

Progress in OEIC (optoelectronic integrated-circuit) technologies is briefly reviewed, and the feasibility of optically integrated ULSI is examined. It is concluded that an overall delay time of 0.1-0.2 ns will be achievable for a bus line in ULSI using optical interconnections, which is more than one order of magnitude faster than the conventional metal wire bus line. Future prospects in optoelectronics are addressed
