【摘要】 本文报告一个测量掺铒光纤非线性折射率的新方法，该方法把掺铒光纤制作成一个环形谐振器。由掺铒光纤非线性导致的位相变化将改变环形谐振器的输出强度，通过输出强度的测量可以得出光纤的非线性折射率。实验结果证实了这种方法的可行性。更多还原

【Abstract】 A new method is reported for measuring the nonlinear refractive index of erbium dopedfibers by means of a ring interferometer(resonator).Phase variation caused by the nonlinear refractiveindex of erbium doped fiber near its absorption peak changes the output signal of this loop,Thenonlinear refractive index can be derived from this variation. Experimental results show the feasibilityof this method.更多还原
