Abstract
A 4 X 4 optical switch performing bi-directional crossbar switching on optical communication signals at 1550 nm is presented and experimented. This switch is expanded from several elementary 1 X 2 optical switches. The switch is made of bulk passive components. Operation is totally polarization independent. The proposed free-space architecture has the features of high compactness, reliability and fast response time compared with common switching solutions.
