Abstract:
An optical device comprising: a first substrate and a second substrate facing the first substrate having a substantially plane surface; an optical path disposed on the first substrate and extends in a plane parallel to the surface of the first substrate; in recess intercepting the optical path; an optical element for modifying light incident thereon, the optical element being moveable within the recess between a first position in which the optical element is located in the path and a second position in which optical element is remote from the path; characterized in that the device comprises a cantilever, formed on the second substrate, for suspending the optical element for movement within the recess between the second and first positions in a direction normal to the surface of the substrate, wherein the optical path is disposed on the first substrate and the cantilever is disposed on the second substrate, and the optical element on the cantilever is aligned for entry in a corresponding recess in the first substrate.
