The development of semiconductor optoelectronics devices will have great impact on optical computing. Progress in semiconductor lasers and photodetectors has revolutionized communication systems and realized new methods of memory, printing and other processes. Further advances in optoelectronic devices, which are now taking a new integrated form, optoelectronics integrated circuit (OEIC). The OEIC will make possible highly versatile optical computing systems in the next century. Recent developments in OEIC technology and future prospects for its application to optical computing are presented.
