调制能力提升的嵌入式石墨烯波导结构
Graphene-embedded waveguide with improved modulation capability
摘要
Abstract
A graphene-embedded waveguide(GEW)with improved modulation capability was proposed,which can be over 2 times larger than that of conventional graphene-on-silicon(GOS)waveguide. More importantly,it is found that the improvement of modulation capability mainly results from the enhanced electric field confine?ment around graphene. Based on this finding,we propose a high-efficient method to optimize the modulation ca?pability. By using this method,the optimization work can be reduced by an order of magnitude. Our work may promote the design of graphene-based electro-optic modulator with high modulation capability.关键词
