摘要：

This letter proposes a new structure of a polarization-independent optical circulator. It is theoretically and experimentally shown that the proposed circulator has high isolation over a wide wavelength range. Insertion loss and isolation of a fabricated four-port circulator have been measured to be less-than-or-equal-to 1.9 and greater-than-or-equal-to 42.3 dB, respectively. Loss ratio over 40.4 dB has been realized.
