Patent ID: 7949217

Claim:
An apparatus for deflecting one or more light beams, comprising: an input deflector operable to: receive a plurality of light beams from a plurality of input channels; and the input deflector comprising a plurality of prism electrodes comprising: a first prism electrode configured to deflect a first light beam received from a first input channel to a first initial deflection angle; and a second prism electrode configured to deflect a second light beam received from a second input channel to a second initial deflection angle, the second light beam distinct from the first light beam, the second initial deflection angle different from the first initial deflection angle, the first input channel distinct from the second input channel; and one or more Bragg gratings, each Bragg grating optically coupled to the input deflector and operable to deflect at least one light beam from the initial deflection angle to an increased deflection angle, the increased deflection angle being at least closer to an output channel of one or more output channels than the initial deflection angle, the Bragg gratings comprising: a first Bragg grating operable to deflect the first light beam from the first initial deflection angle to a first increased deflection angle, and to pass through the second light beam without deflection; and a second Bragg grating operable to deflect the second light beam from the second initial deflection angle to a second increased deflection angle, the second initial deflection angle different from the first initial deflection angle, and to pass through the first light beam without deflection.
