摘要：

A new fiber-embedded optical isolator with a low forward loss has been developed. The isolator consists of thermally diffused expanded core fibers, laminated polarizers, and a Faraday rotation garnet. The isolator needs no lens elements. Backward and forward losses at 1.3-mu-m wavelength are 44 and 0.9 dB, respectively.
