A crossbar switch (500) with input optical fibers (571, . . . 586) and output optical fibers (511, . . . 526) having ends connected to transmitters (551, . . . 554) and receivers 561, . . . 564), respectively, and other ends in linear arrays (545, 546) that are adjacent to linear micro lens arrays (540, 542) and a linear spatial light modulator (530) with light emitted from an input fiber end reflected back into an output fiber end for pixels deflected in one direction in the spatial light modulator (530) and lost for pixels deflected in another direction. Other embodiments include reflection from a pixel directly back into the same fiber which is bifurcated.
