An optical switching arrangement is provided with continuously rotating mirros (8, 9, 10) which are preferably micro-machined, each deflecting light from an associated optical input (2, 3, 4), preferably mono-mode optical fibres, towards optical outputs (5, 6, 7) in sequence. Further pairs of continuously rotating micro-machined mirrors (11/12, 13/14, 15/16) are each associated with respective optical outputs (5, 6, 7) to stabilise the direction of light that is to be coupled with the optical outputs so that better coupling is achieved. The optical switching apparatus provides a faster switching arrangement and lower signal loss. |
