我们从理论上研究了基于刻有倾斜布拉格光栅的平行平面波导阵列的器件。我们演示了偏振相关的 N×N+1 线性耦合器。确定性切换可以通过输入光束的相干控制和优化的光栅变迹来实现。
We investigate theoretically devices based on arrays of parallel planar waveguides inscribed with tilted Bragg gratings. We demonstrate polarization-dependent N by N+1 linear couplers. Deterministic switching can be achieved by coherent control of input beams with optimized apodization of the gratings.
