摘　　要：Beam splitters play a crucial role in a wide range of optical systems.A typical beam splitter consists of several transport channels,and an input beam from one channel is split into multiple output beams coupled into other channels.For traditional beam splitters,their transportation channels(either in free space or waveguides)are reciprocal,being sensitive to various perturbations caused by defects and obstacles.
