光子晶体腔的超快速非线性光学调谐

Ultra Fast Nonlinear Optical Tuning of Photonic Crystal Cavities

Ilya Fushman, Edo Waks, Dirk Englund, Nick Stoltz, Pierre Petroff, Jelena Vuckovic

摘要:

我们演示了快速(高达20 GHz),低功耗(5 $μW$)调制的光子晶体(PC)腔中的GaAs含InAs量子点。利用带外皮秒激光脉冲注入自由载流子,实现了腔体共振蓝移的快速调制。慢调谐的几个线宽由于激光诱导加热也被证明。

英文摘要:

We demonstrate fast (up to 20 GHz), low power (5 $μW$) modulation of photonic crystal (PC) cavities in GaAs containing InAs quantum dots. Rapid modulation through blue-shifting of the cavity resonance is achieved via free carrier injection by an above-band picosecond laser pulse. Slow tuning by several linewidths due to laser-induced heating is also demonstrated.
