Simulated Characteristics of a Nonlinear Directional Coupler Based Optical Switch. Characteristics of Nonlinear Directional Coupler Abstract-This paper presents a nonlinear directional coupler for optical power switching. The theoretical study has been done to study the coupling characteristics of the nonlinear directional coupler. Variation of the coupling coefficients with wavelength have been done, and found that, out of all four coupling coefficients, nonlinear coupling coefficient (equivalent to selfphase […]
