ABSTRACT:
An architecture for a compact, 1.times.N optical switch. The switch package receives light from an input optical fiber (12b), which is directed over a well or gap at the bottom of which lies a micromechanical structure (10). If the structure is in an unaddressed state, the light travels into an in line output optical fiber (12a). If the structure (10) is in an addressed state, it intercepts the light and reflects it out of the plane of the input optical fiber to an offset mirror (24). The offset mirror (24) then reflects the light to one output fiber (16a, 16b). The offset mirror may have steps such that more than one optical fiber could become the output fiber, depending upon the structure's position.
