Photonic molecular memory

Abstract

Photonic molecular memory based on the direct interaction of photons with　organic molecules is one of the most promising approaches to future memory, with a density of >T bits/cm2 and a read/write speed of >100 G bits/s. Our recent results are presented on novel materials showing absorption changes in the wavelength range of about 500-2000 nm with response times of about 0.2 to 3 picoseconds due to photoinduced electron transfer and reverse reactions, and an all-optical reflection type control of intensity and phase by photoinduced complex refractive index changes of the guided-wave mode thin films.
