摘要：

A waveguide optical isolator based on nonreciprocal interference is demonstrated. Ridge waveguides are fabricated in a Mach-Zehnder configuration on a single film of bismuth-, lutetium-, neodymium-iron garnet. With this design, no polarizers are required to achieve extinction in the backward propagation direction. This isolator exhibits a 19 dB extinction ratio at lambda=1.54 mu m. A flat wavelength dependence, to within 2 dB, has been observed in the range between 1.49 and 1.57 mu m. (C) 2000 American Institute of Physics. [S0003-6951(00)02416-5].
