| Abstract | |
This work presents a capacitive modulator design and modeling of a new waveguide architecture using silicon and poly-si technologies. We use a methodology involving the entire lumped-type modulator design process, from the optical design to the small-signal RF analysis. By means of geometric and physical parameters adjustments, the trade-offs among several figures of merit are analyzed in this paper. Due to the waveguide configuration, it is shown that the modulator can improve the trade-off between Vp and bandwidth compared to the state-of-the-art for this kind of device. For instance, the best combinations are Vp 1V@ 20.4GHzandVp = 5.7V@31 GHz, with equivalent optical losses of 3 dB and 1.1 dB, respectively. (AU) | |
