Abstract
We propose an optical multicarrier generation technique using silicon micro-ring modulator (MRM) and analyze the scheme. Numerical studies have been done for three types MRMs having different power coupling coefficients. The proposed scheme is found to generate four optical carriers having 12.5Â GHz spacing. According to simulation, the maximum side-mode-suppression ratio (SMSR) of ~16.3Â dB with flatness of ~0.2Â dB is achieved by using this scheme. The minimum extinction ratio (ER) of the generated carriers is found to be more than 35Â dB. We also propose modulator driver circuit to generate RF signal, which is needed to generate multicarrier using MRM. The effect of coupling coefficient on the SMSR of the generated carriers is also investigated.
