We investigate and compare the performance of four optical transport schemes for distributing Local Multipoint Distribution Service (LMDS) signals using an optical fiber backbone.

In some information processing architectures, the role of various analog and digital data comparisons is very important. In this letter, we proposed a multi-bit data comparison scheme. The scheme is based on the switching property of optical nonlinear material. Ultrafast operational speed larger than gigahertz can be expected from this all-optical scheme.展开更多
