Optically Triggered Digital OEIC

چکیده
The technology of high speed optoelectronics has been rapidly developed in the past decade, and possible application of them to digital signal processing has been investigated, including the authors' effort to implement optically controlled digital integrated circuits [1],[2]. The advantage of utilizing optical technology supplementing the conventional electronic technology lies in the fact that this is promised to have much superior capability in transmitting data, being free from CR time constant constraint. Part of this statement is enriched further by the recent development of short pulse generation from compact semiconductor lasers [3],[4],[5], enabling sub-picosecond pulse generation at arbitrary repetition frequency. The greatest challenge to be overcome is the achievement of cost-effectiveness in manufacturing data transfer module at higher bitrates. For telecommunication systems, the high capacity data flow enables the use of high performance, but costly hardware. On the other hand in massively parallel processing systems, a number of connecting modules must be installed with high reliability and reasonable cost. Therefore new design concept must be introduced. The present study aims at the realization of optically controlled integrated circuit, reducing the burden of electrical pulse distribution wiring problems.
