摘要:

我们证明了单个量子点与GaAs基L4/3型光子晶体纳米腔之间的强耦合。L4/3腔支持高的理论Q因子(~8{ \times } 10 ^6)、小的模体积(~ 0. 32(λ/n)^3)和电场分布,其中最大电场位于主体介电材料内,这有利于与量子点的强耦合。我们制作了L4/3腔,用光致发光测量观察到超过80,000的高Q因子。通过观察光谱中的明显反交叉,我们证实了单个量子点与Q因子为33,000的L4/3腔之间的强耦合。

英文摘要:

We demonstrate strong coupling between a single quantum dot and a GaAs-based L4/3-type photonic crystal nanocavity. The L4/3 cavity supports a high theoretical Q factor (~8{\times}10^6), a small mode volume (~0.32 (λ/n)^3), and an electric field distribution with the maximum electric field lying within the host dielectric material, which facilitates strong coupling with a quantum dot. We fabricated L4/3 cavities and observed a high Q factor over 80,000 using photoluminescence measurement. We confirmed strong coupling between a single quantum dot and an L4/3 cavity with a Q factor of 33,000 by observing a clear anti-crossing in the spectra.
