Abstract

We have developed an optically differential reconfigurable gate array (ODRGA-VLSI) to realize no-overhead and fast reconfigurable devices. The no-overhead and fast reconfiguration capability of a fabricated VLSI chip has been confirmed experimentally. However, to date, evaluation of nanosecond reconfiguration speed with an entire system combining a VLSI chip, spatial light modulators (SLMs) used as optical memories, and lasers has never been conducted. Therefore, this paper presents an entire ODRGA system including SLMs, pulse lasers, and an ODRGA-VLSI chip. Results show a 220 ns fast reconfiguration and circuit performance on the gate array.
