Optoelectronic microprocessors built using existing chip manufacturing

Researchers have produced a working optoelectronic chip that computes electronically but uses light to move information. The chip has 850 optical components and 70 million transistors, which, while significantly less than the billion-odd transistors of a typical microprocessor, is enough to demonstrate all the functionality that a commercial optical chip would require.
