Abstract

In this paper, an example of a silicon telecommunication modulator based on micro-ring Resonator is designed. In order to achieve high bandwidth, the coupling coefficient must be improved. This issue is investigated by changing the coupling coefficient for different Coupling Lengths and gaps between the bass waveguide and the ring. The optimal Coupling Length was calculated. By numerical calculation, the impurity and carrier distribution in a PN phase modulator are investigated and various effects such as doping distance change, doping rate change and its effect on refractive index and absorption changes are investigated. By improving the modulator parameters and optimizing the coupling coefficient of the ring modulator the DC gain is enhanced and the electro-optical response became more stable. Comparisons have also been made to similar modulators and bandwidth has been improved up to one order.
