摘要：

The operation of a waveguide-type optical circulator is demonstrated for the first time. The isolation of 3 dB, which is defined by the transmission ratio of forward to backward propagation, has been achieved in the circulator which comprises (LuNdBi)3(FeAl)5O12 nonreciprocal phase shifters. © 1990, The Institution of Electrical Engineers.
