Abstract

Progress in optical computing, optical communication and optical information processing depends on a large extent of the availability of fast all-optical switches. Most of the all-optical switches utilize nonlinear FP cavity^1,2,3. Its absorptive loss is very large because of working on the resonant wavelength, and the switching time is districted by the response time of cavity. In 1990 K. W. Beeson⁴ presented a novel all-optical switch based on the triplet-triplet absorption in Eosin Y using a CW laser as a pump beam, and obtained μs scale switching time. We developed this kind of switches in C₆₀⁵ whose switch off time was about 250 ns which depends on the lifetime of the first triplet excited state.
