Whispering gallery modes in cylindrical integrated optics microcavities have, for what is to our knowledge the first time, been mapped with a photon scanning tunneling microscope. Optical images were obtained with a spatial resolution of 50 nm. By combination of information on the spatial optical distributions with wavelength-dependent measurements, an unexpectedly rich variety of intracavity phenomena, such as polarization conversion and interference of copropagating and counterpropagating modes, could be directly observed. A quantitative comparison of the experimental data with computer simulations results in a comprehensive understanding of the various whispering gallery modes inside the microcavity.
据我们所知，首次使用光子扫描隧道显微镜对圆柱形集成光学微腔中的回音壁模式进行了测绘。获得了空间分辨率为50纳米的光学图像。通过将空间光学分布信息与波长相关测量相结合，可以直接观察到各种意想不到的丰富腔内现象，如偏振转换以及同向和反向传播模式的干涉。将实验数据与计算机模拟进行定量比较，从而全面了解微腔内的各种回音壁模式。
