摘要：

A low-loss large-angle waveguide bend structure utilizing a low-index microprism is proposed. Using the principle of phase front compensation, a simple and efficient rule for the low-index prism is derived, Field distortion due to the prism is discussed and an optimized prism design is also proposed. Simulated normalized transmission efficiency of the proposed waveguide bend is as large as 99.1% for a bend angle of 10 degrees, Moreover, waveguide bends with high- and low-index prisms are compared for reference.
