介绍了利用非互易相移实现光隔离器的实验研究。该隔离器具有由锥形耦合器、非互易移相器和互易移相器组成的光学干涉仪。隔离器，设计为一个1.55微米的波长，制造调查每个组件的特性。测量了锥形耦合器的分支特性和耦合特性。还评估了非互易和互易相移。通过对干涉仪施加外磁场，我们证实了干涉隔离器中的非互易相移。
The experimental study of an optical isolator by use of a nonreciprocal phase shift is demonstrated. The isolator has an optical interferometer composed of tapered couplers, nonreciprocal phase shifters, and a reciprocal phase shifter. The isolator, designed for a 1.55-microm wavelength, was fabricated to investigate the characteristics of each component. The branching and coupling characteristics of the tapered coupler were measured. The nonreciprocal and reciprocal phase shifts were also evaluated. By applying an external magnetic field to the interferometer, we confirmed the nonreciprocal phase shift in the interferometric isolator.
