| Abstract |
This paper proposes the performance optimization methodology of 25-Gbps depletion-type silicon-ring modulators, and experimentally verifies its effectiveness. A model is proposed that can describe the dependence of the dynamic modulation characteristics on the depletion-type silicon-ring modulator device structure. The model parameters that influence the ring modulator performance are identified, and their dependence on the device structure is investigated. With this, the optimal device structure that results in the best 25-Gbps eye diagrams is determined. The experimental results confirm the accuracy of our design optimization method. |
