Simulation of integrated coupled nonlinear microring resonators all-optical pulse restorer

Résumé

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 suitable for all-optical regeneration (reshaping) in the frequency and the time domains. The fully integrated device is based on 2 cascaded sets of finite chains of 3 coupled nonlinear identical microring resonators side coupled with 3 straight waveguides. The microrings are constituted by the same instantaneous, dispersive, local Kerr material. The first set suppresses the noise in "0" and the second limits the amplitude fluctuations in "1" of return-to-zero optical data streams. For a device made in p-toluene sulphonate (PTS) with n2 = 2.2×10-12 cm2/W with linear losses a = -5 dB/cm and nonlinear losses a2 = 0.5 cm/GW and considering amplitude, jitter and width fluctuations we evaluate an amplitude Q-factor improvement of 4.94 dB for a data rate of 40 Gb/s and input intensity n2/0 = 5 × 10-4. Since we take advantage from field enhancement at resonance, this integrated reshaper could be much smaller than other gates based on nonlinear fibers or waveguides.
