We constructed a metallic air-gap planar microcavity of a prism/metal/dye layer/air gap/metal, which allowed exciations of enhanced evanescent waves. A small mechanical variation of the air-gap distance was sensitively detected with modulation of the interference of light through the air gap. The demonstration shows that the air-gap distance is controlled in submicron scale. Emission with spectra modulated by the air-gap distance could not be observed from the microcavity with dye molecules excited by light irradiation. On the other hand, we have found that photoluminescence spectra for organic thin films on metal depended remarkably on emission angles.

我们构建了棱镜/金属/染料层/气隙/金属的金属气隙平面微腔，它允许激发增强的倏逝波。通过调制穿过气隙的光的干涉，可以灵敏地检测到气隙距离的微小机械变化。演示表明，气隙距离被控制在亚微米尺度。在光照射激发染料分子的微腔中无法观察到由气隙距离调制的光谱发射。另一方面，我们发现金属上有机薄膜的光致发光光谱很大程度上取决于发射角。
