Abstract
A novel approach for measuring the nonlinear refractive index of an optical fiber utlizing the bistable behavior of the double coupling optical fiber ring resonator was proposed and investigated. The switch-off or switch-on power decreases with an increase in the nonlinear refractive index n2 (m2/W), and the dependence of swith-off or switch-on power on the nonlinear refractive index was analyzed numerically. Simulation results showed that the switch-off power and switch-on power (in dBW) decreased linearly with log10(n2) in a 100-m-length fiber ring resonator, when n2 changed from 3.2 × 10−20 m2/W to 2.5 × 10−17 m2/W or nearly n2 = 3.2 × 10−20 m2/W. These mean that high accuracy as well as large-scale nonlinear refractive index measurement can be achieved by the proposed approach.
Highlights
The optical nonlinear resonator has been attracting greatly attention due to its variety of possible operating regimes, including bistability, period-doubling, or chaos [1]
We proposed and investigated a nonlinear refractive index measurement approach utilizing the bistable behavior of the double coupling optical fiber ring resonator structure
From the point of view of the application, we further investigated the relationship between the switch-on power and the nonlinear refractive index when the nonlinear refractive index varied in a small range
Summary
The optical nonlinear resonator has been attracting greatly attention due to its variety of possible operating regimes, including bistability, period-doubling, or chaos [1]. Optical bistabiltiy has been studied widely over the past years, and numberous applications such as differential amplification, optical thresholding, or all-optical switching have been demonstrated [3,4,5,6]. This interesting behavior originates in an optical Kerr effect that the refractive index of an optical fiber is changed depending on the optical intensity. We proposed and investigated a nonlinear refractive index measurement approach utilizing the bistable behavior of the double coupling optical fiber ring resonator structure. Photonic Sensors scale nonlinear refractive index measurement could be achieved by this proposed approach
