基于等离子体结构的太赫兹石墨烯电光调制器的机理分析
Mechanism analysis of terahertz graphene electro-optic modulator with plasma structure
摘要
Abstract
Based on the theory of plasmon resonance,we present a photon plasma ridge waveguide consisting of a metal/graphene/Al2O3/graphene stacking structure. The modulation performance is optimized through the design of the waveguide and plasma structures by analyzing the microscopic mechanism of photoelectric reaction. A low-insertion-loss near-infrared electro-optic modulator with a modulation rate of 730 GHz,energy consumption of 0. 7 fJ/bit,and 3-dB bandwidth of 3. 66 THz is achieved.关键词
