提出了一种利用宽禁带II-VI族量子威尔斯阱子带间跃迁的全光开关。该波导具有单独的限制异质结构(SCH)和亚微米高台面波导更强的光限制。当开关消光比为10 dB时,控制脉冲能量降低了39%,同时保持了亚皮秒响应。
An all-optical switch using intersubband transition in wide-gap II-VI-based quantum wells in an improved waveguide structure is presented. The waveguide exhibits a separate confinement heterostructure (SCH) and submicron high-mesa waveguide for stronger optical confinement. A reduction of 39% is achieved in control pulse energy for a 10 dB switching extinction ratio while maintaining a subpicosecond response.
