| Abstract: | Theoretical analysis of electronic and photonic characteristics for silicon based electro-optic ring modulator was presented. Expression for the speed of optical modulator was determined through theoretical derivation, indicating the important role of optical resonator characteristic to the speed of modulator. The result reveals modulate speed is related to Q and width of waveguide. Adopting this result,the characteristics of electro-optic ring modulator can be optimized. In addition,the speed limit of such... |
