摘要：

A 1.5-mu m nonreciprocal-loss waveguide optical isolator having improved transverse-magnetic-mode (TM-mode) isolation ratio was developed. The device consisted of an InGaAlAs/InP semiconductor optical amplifier waveguide covered with a ferromagnetic epitaxial MnSb layer. Because of the high Curie temperature (T-c=314 degrees C) and strong magneto-optical effect of MnSb, the nonreciprocal propagation of 11 - 12dB/mm has been obtained at least up to 70 degrees C.
