Abstract

We numerically demonstrate the feasibility of constructing an all-optical pulse restorer by using a microresonator structure with Kerr nonlinearity. We obtain a clear nonlinear power transfer curve capable of improving the signal-to-noise ratio and reducing the bit error rate for digital signals. Since we take advantage of field enhancement at resonance, this integrated reshaper could be much smaller than other gates based on nonlinear fibers or waveguides.
