A optical Processeur is an electronics component of which the goal is to treat numerical data transformed into light signals. The transformation is done by lasers diode, then by photodetectors.
- the first optical DSP (ODSP) was carried out by the Israeli company Lenslet in 2003. Enlight64 was able to calculate 240 GMAC/s. Its Enlight256 successor, of a computing power of 8000 GMAC/s, was presented to the military living room MILCOM (Military Communications Conference) with Boston, the United States, in October 2003. These processors use lasers diode VCSEL, an optical matrix SLM of 256x256, and photodiodes. Their work frequency is of 125 MHz.
