摘要

本文演示了通过调节温度来控制耳语通道模式(WGM)的谐振频率。我们使用单模光纤来制造微球。将光纤的聚合物涂层剥离，然后用聚焦的CO/sub /激光束将尖端熔化，形成一个带茎的球体。用温度计监测微球的温度。将线宽< 300khz的可调谐外腔二极管激光器照射在微球上。来自微球的散射光被显微镜物镜收集并成像到针孔上，以便雪崩光电二极管选择性地观察微球的边缘。我们对激光频率进行扫描，在780 nm处测量了几十GHz范围内的散射光谱。

Fine frequency tuning of a microspherical cavity by temperature control

In this paper, resonant frequency control for the whispering-gallery modes (WGM) is demonstrated by adjusting the temperature. We used single-mode optical fiber for the fabrication of the microsphere. The polymer coating of the fiber was stripped, and then the tip was melted by a focused CO/sub 2/ laser beam to form a sphere with a stem. The temperature of the microsphere was monitored by a thermometer. A tunable external-cavity diode laser (linewidth<300 kHz) was illuminated on the microsphere. The scattered light from the microsphere was collected by a microscope objective and imaged onto a pinhole so that the edge of the microsphere was selectively observed by an avalanche photodiode. We scanned the laser frequency to measure the scattering spectra over tens of GHz range at 780 nm.
