ABSTRACT:
A switch for coupling a row of three input/output optical fibers. The switch is based on a spatial light modulator device, having a tiltable mirror element, with a grazing mirror layer, a lens layer, and a fiber holder layer assembled on top. The grazing mirror layer directs light to or from the outer fibers to or from the tiltable mirror and permits the fiber holder layer to hold the axes of the ends of the fibers parallel to each other. The lens layer is interposed between the fiber holder layer and the grazing mirror layer for coupling light into and out of the fibers.
