| Research Abstract |
To realize high speed parallel processing, parallel optoelectronic computing system which has processing element (PE) and optical interconnection between PEs is one of effective methodologies. In this research we construct high speed massively parallel processing system with our original PE by electronic circuit and optical interconnection experimentally, and realize some meaningful operations by the system.
To construct the system actually, we arranged the needed specification for each elementally tchnology, and decided the algorithms to make it work. And we reexamined the performance of each elementally technology, and obtained the fundamental data for the improvement. Therefore the limitation in present technology and the predictin of the performance in future are explicit.
In fact, we made 16*16 PE array using LSI,and developed the alorithms to execute on it. Measuring the actual performance of computer generated hologram (CGH), we obtained the fundamental data to improve.
Especially we specified optical devices (emitting detector array, photo detector array, spatial light modulator (SLM), high resolution display, et.al.) to satisfy our request. As a result we found the writing time to liquid crystal spatial light modulator is the neck of system.
Developing the processing element and the algorithms, we paid attention to the analysis of the algorithms which consider optical interconnection.In order to correspond to the wavelength of the surface emitting laser diode array (VCSEL) using as emitting elements, we changed the wavelength of optical device contains SLM,However we obtained good experimental results.
