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 cavity1,2,3. 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.
