NTT Develops Optical RAM

Researchers at Nippon Telegraph and Telephone (NTT) have developed an optical random access memory (RAM) device that integrates ultrasmall optical memories based on photonic crystal nanocavities.

Specifically, NTT Nanophotonics Center has succeeded in large-scale integration of over-100-bit optical memories with a wavelength division multiplexing (WDM) configuration. This was enabled by novel optical nanocavities based on a photonic crystal. The scale of this integration demonstrates the feasibility of optical random access memories for optical processing.

Results of this research will be published this week in the UK science journal “Nature Photonics”.
