| 摘要 |
An optical circulator for transmitting light along a first optical path from a first optical port to a second optical port and along a second optical path from the second optical port to a third optical port, an optical interface in the first and second optical paths that passes the first beam but deflects the second beam to a highly reflective surface, wherein the plane of the highly reflective surface is at an angle to the optical interface such that the second beam is deflected from the highly reflective surface to the third port, and wherein the first port and the third port can be configured to utilize the same GRIN lens.
