摘要 |
This invention discloses an optical circulator compatible with optical glass fiber transmission lines in optical communications in the wave length range of 1.0 DIFFERENCE 1.7 microns. An optical circulator embodiment of the invention utilizes a magneto-optic circulator cylinder with the entry and reflective ends, at least three coupling glass-fiber transmission lines being connected to the entry end. The biasing magnetic field is applied in parallel with the common axis. This circulator embodiment of the invention possesses advantages in consisting of minimal constituents, and in being easy to make and simple to adjust.
