我们研究了作为一个小型化的高分辨率光谱设备的球形微谐振器阵列的属性。将由聚甲基丙烯酸甲酯制成的十六个球形微球放置在用作光波导的显微镜载玻片上。将可调谐窄带激光源的光耦合到该载玻片中，使得在放置谐振器的载玻片的顶侧上激发倏逝波。这种倏逝场在阵列中产生了一种特定的强度图案，这种图案敏感地依赖于波长。校准后，该图案由CCD相机记录，并用于识别波长，分辨率为R，类似于λ/Δ λ = 7 × 10（4）。(c)2007年，美国光学学会。
We investigated the properties of an array of spherical microresonators used as a miniaturized high-resolution spectroscopic device. Sixteen spherical microspheres made from polymethyl methacrylate were placed on a microscope slide serving as an optical wave guide. Light of a tunable narrowband laser source was coupled into this slide so that an evanescent wave was excited on the topside of the slide, where the resonators were placed. This evanescent field generated a particular intensity pattern in the array that depended sensitively on the wavelength. After calibration, that pattern was recorded by a CCD camera and used to identify the wavelength with a resolution of R similar to lambda/Delta lambda = 7 x 10(4). (c) 2007 Optical Society of America.
