چکیده انگلیسی
A novel method for measuring the nonlinear refractive index of an optical fiber using a spectral ratio between the modulation frequency and a harmonic component in a modulated optical fiber ring resonator (OFRR) is proposed. The spectral ratio between the modulation frequency and the 2nd-harmonics generated by phase-modulation through the OFRR is increased with increasing the input light power and has peaks above 5Â W input power, however, the peaks was shifted to the lower input power below 1Â W by averaging taken into account of the phase distribution. A experimental setup consisted of an OFRR system and an Ar-laser as a pump light source was used to determine the nonlinear refractive index of an optical fiber. In the experimental results, the peaks of the spectral ratio as a function of the input power was found out at 0.8Â W and 0.45Â W of the input power corresponding to the input source line at 488.0Â nm and 514.5Â nm, respectively. The profile was similar to that obtained by the simulation and the nonlinear refractive index of a optical fiber was determined as 1.0Â ÃÂ 10â22Â m2/V2 by a relationship between the input power giving the peak and the nonlinear refractive index.
