Abstract :
In this paper a silicon micro-ring resonator assisted 16-QAM modulator suitable for WDM application has been proposed. We have demonstrated successful operation of the proposed 16-QAM modulator operating at 10 Gbps and 20 Gbps bit-rate per channel for a three channel WDM system. The performance of the modulator for different channel separation has also been investigated using detailed numerical simulations.
