【摘要】 本文概述了量子阱电吸收光调制器设计的整个过程,从量子阱材料设计,到器件的光波导设计和微波特性设计,并给出了使用剥离法、湿法刻蚀技术制作InP基量子阱电吸收调制器的初步实验结果。InP基窄带隙量子阱材料设计相对能隙较大的GaAs量子阱材料必须考虑能带耦合效应,材料设计、光波导设计和微波特性设计是相互影响的。更多还原

【Abstract】 The whole design procedure of multiple quantum well (MQW) electroabsorptionmodulator, from quantum well material to device optical waveguide and microwaveproperties, is briefly summarized. And the elementary experiment result of MQWelectroabsorption modulator using lift-off technology and wet etching is presented. Thesimulation of InP-based narrow-band quantum well is more complicate than that ofGaAs-based quantum well. The couple of the bands have to be considered. The propertiesof material, optical waveguide and microwave properties would be influenced each other.更多还原
