摘要:

我们提出了一种嵌入量子点的氧化物孔径微腔,该微腔利用三个接触设计来独立地调谐量子点波长和腔模的双折射。观察到$\sim$ 5 GHz的偏振分裂调谐。对于典型的微腔偏振分裂,该方法可以用来实现完美的偏振简并,这是光子量子门的许多基于偏振的实现所需的。嵌入的量子点波长可以被调谐成与腔共振,而与偏振调谐无关。

英文摘要:

We present an oxide aperture microcavity with embedded quantum dots that utilizes a three contact design to independently tune the quantum dot wavelength and birefringence of the cavity modes. A polarization splitting tuning of $\sim$5 GHz is observed. For typical microcavity polarization splittings, the method can be used to achieve perfect polarization degeneracy that is required for many polarization-based implementations of photonic quantum gates. The embedded quantum dot wavelength can be tuned into resonance with the cavity, independent of the polarization tuning.
