【Abstract】 This paper reports a polarizationindependent optical circulator having high isolatity over a wide wavelength range. A 3port optical circulator has been manufactured with singlemode fibers. Its insertion loss and isolatity have been respectively measured to be ≤1 dB and ≥48 dB at the center wavelength of 1.55 μm. Its polarizationdependent loss is ≤0.2 dB , crosstalk is ≤-50 dB, and return loss ≥50 dB.更多还原
