摘要:

我们在一个曲率半径为 R = 17.7(3) μm、精细度 F ≈ 1000 的开放光学微腔中测量宽带发射体的荧光光谱。该几何结构能够同时测量发射光谱随腔长的变化,相比仅固定波长或仅固定腔长的测量具有若干优势。我们展示了光学穿透深度对腔模的作用,并提供了用于分析该问题的实用工作方程。此外,我们展示了在较小的腔长扫描范围内测量腔模之间耦合的能力。通过测量这些随腔长变化的腔发射光谱,我们由此获得了该光学微腔丰富而完整的图像。

英文摘要:

We measure the fluorescence spectrum of broadband emitters in an open optical microcavity with radius of curvature R = 17.7(3) um and finesse F ~= 1000. This geometry enables a combined measurement of emission spectra versus cavity length, which has several benefits over measurements at fixed wavelength or fixed cavity length alone. We demonstrate the role of the optical penetration depths on the cavity modes and provide practical working equations for its analysis. Furthermore, we show the ability to measure the coupling of cavity modes within a small scan range of the cavity length. By measuring these cavity emission spectra as a function of cavity length, we thus obtain a rich and complete picture of the optical microcavity.
