    • A device includes an -optical splitter comprising a plurality of splitter outputs. The splitter outputs are out of phase and include a non-uniform phase front The device Includes a one- dimensional phase compensation array communicating with the optical splitter. The phase compensation array receives the non-uniform phase front and outputs a uniform phase front The phase compensation array includes a- plurality of array outputs. The device includes a tunable linear gradient phase shifter communicating with said phase compensation array to impart a linearly- varying phase shift across said plurality of array outputs, thereby steering a beam along a first angle- in a first plane. The device includes a waveguide grating out-coupler communicating with said linear gradient phase shifter, and a Uniterm phase shifter communicating with, the waveguide grating out-coupler. The uniform phase shifter steers the flat phase front along a second angle in a second plane perpendicular to said first plane.
    • 一种设备包括包括多个分路器输出的光分路器。 分离器输出相位相反,包括非均匀的相位正面该器件包括一个与分光器通信的一维相位补偿阵列。 相位补偿阵列接收非均匀相位前沿并输出均匀相位前沿。相位补偿阵列包括多个阵列输出。 该装置包括与所述相位补偿阵列通信的可调谐线性梯度移相器,以在所述多个阵列输出端上施加线性变化的相移,由此在第一平面中沿第一角度引导光束。 该装置包括与所述线性梯度移相器通信的波导光栅输出耦合器以及与波导光栅输出耦合器通信的Uniterm移相器。 均匀移相器在垂直于所述第一平面的第二平面中沿第二角度转动平相前沿。
