An mxn optical switch is formed on a semiconductor substrate. Grooves are etched at the edges of the substrate to accommodate input and output optical fibers so that the output fibers are placed orthogonal to the light paths of the input fibers. An array of photodetectors is provided at an edge opposite to that of the input fibers to receive the input signals. At each crosspoint defined by the input and output fibers is an electromechanically actuated mirror which in one state permits passage of light from its associated input fiber, and in another state deflects the light to its associated output fiber.
