Abstract
A planar 2×2 switch is provided for controllably coupling first and second input channels to first and second output channels. The switch includes a first reflector that is movable between a first position and a second position. When the first reflector is in its second position, it reflects light from the first input channel to the second output channel and reflects light from the second input channel to the first output channel. When the first reflection is in its first position, it does not affect the optical beams in the switch. Instead, these beams are reflected by a second reflector which has two reflective surfaces. The second reflector reflects light from the first input channel to the first output channel and reflects light from the second input channel to the second output channel. Switches having a larger number of input and output channels are also provided.
