Abstract:
An apparatus for switching an optical signal from a first optical path to a second optical path, the apparatus comprising:a substrate; a micro-machined platform formed by a lithography process onto the substrate, the micro-machined platform being adapted to rotate relative to the substrate; an actuation mechanism to cause the platform to rotate from a first position to a second position relative to the substrate; and an optical path network having a first input and a second input, the optical path network coupled to the platform such that the optical path network rotates with the platform, whereby when the platform is in the first position, the optical signal enters the first input and travels along the first optical path in the optical path network, and when the platform is in the second position, the optical signal enters the second input and travels along the second optical path in the optical path network.
