Abstract

We propose a new RING RESONATOR side-coupled M-Z interferometer all-optical switch through the pumped nonlinear directional coupler. By controlling pump power P to lead the coupler reflectivity r approaching to 1, the resonator finesse will be enhanced dramatically, and then the minimum SWITCHING POWER in silica-based practice devices can be obtained. As a sample, we use a nonlinear coupler made by two ERBIUM-DOPED FIBERs, and launch a 514.5nm-pump light into one of the cores to make the reflective- index difference between two cores. Based on the asymmetric-coupler theory, we simulate the relationship between r and P, and show that the required pump power is only 0.8Mw for r →1.
