Analysis of blocking performance of the multi-wavelength optical switching without optical buffer;

An effective routing algorithm is presented for the multi-stage rearrangeable optical switching network.

Then, by explaining that the optical "micro electro-mechanical systems (MEMS)" would be the best devices, the paper describes their applications in wavelength routers, in optical crossconnects, and in optical switching successively.
