Abstract

We demonstrate a novel all-optical static RAM cell that exploits wavelength diversity in the incoming optical streams towards reducing the number of active elements. The circuit requires only three semiconductor optical amplifiers-cross gain modulation gates for successful read/write operation, yielding a 25% reduction in power consumption compared to state-of-the-art configurations. Proof-of-concept experimental verification is presented at 8 Mb/s using fiber-interconnected off-the-shelf bulk components.
