摘要

我们系统地评价了量子点光子晶体纳米腔的质量因子。由于未耦合的量子点在纳米腔内的重吸收效应，所测得的Q因子对腔模式失谐能量对量子点非均匀展宽非常敏感。通过对腔模失谐的抑制，实现了超过10000的高Q因子和超低阈值激光。

Role of Re-absorption Effect to Quality Factor in Quantum-Dot Photonic-Crystal Nanocavities

We have systematically evaluated quality (Q) factor in quantum-dot (QD) photonic-crystal nanocavities. The measured Q factor was very sensitive to the detuning energy of the cavity mode to QD inhomogeneous broadening due to the re-absorption effect of the uncoupled QDs within the nanocavity. We achieved a high Q factor of over 10,000 and an ultra-low threshold lasing by the detuning of the cavity mode and the suppression of this effect.
