ABSTRACT:
According to one embodiment, an apparatus for deflecting light beams comprises an input deflector and one or more Bragg gratings. The input deflector receives light beams from input channels, and deflects each light beam to an initial deflection angle. A Bragg grating deflects at least one light beam from the initial deflection angle to an increased deflection angle, where the increased deflection angle is at least closer to an output channel than the initial deflection angle.
