摘要:

我们使用连续波紫激光器对GaInP光子晶体腔进行了空间相关的调谐。通过激光加热光子晶体膜获得局部调谐。腔共振位移测量不同的泵的位置和两种环境气体:氦和氮。我们发现,膜中诱导的温度分布的宽度在很大程度上取决于环境气体的热导率。对于He气体,预测了2.8 μ m的窄空间宽度的温度分布,并在实验中得到了验证。

英文摘要:

We perform spatially dependent tuning of a GaInP photonic crystal cavity using a continuous wave violet laser. Local tuning is obtained by laser heating of the photonic crystal membrane. The cavity resonance shift is measured for different pump positions and for two ambient gases: helium and nitrogen. We find that the width of the temperature profile induced in the membrane depends strongly on the thermal conductivity of the ambient gas. For He gas a narrow spatial width of the temperature profile of 2.8 um is predicted and verified in experiment.
