回音壁模式花生腔制备及其定向发射特性
Preparation of Whispering Gallery Mode Peanut-shaped Cavity and Its Directional Emission Characteristics
摘要
Abstract
The deformed whispering gallery mode(WGM)microcavity combines the advantages of high quality fac-tor and rich internal mode paths,demonstrating significant research value in chaotic dynamics,sensing detection,and directional emission.This paper presents a hybrid fabrication method combining traditional hydrogen-oxygen flame heating and carbon dioxide laser heating.Initially,two optical fibers were fused and stretched together using hydrogen-oxygen flame heating.Subsequently,secondary fusion stretching was performed through CO2 laser heating to fabricate a peanut-shaped WGM microcavity array.Experimentally,we investigated the effects of stretching dis-tance during flame heating and the spacing between two CO2 laser heating positions on the dimensions and morpholo-gy of the peanut-shaped cavities.Using a tapered fiber coupling,we explored coupling intensities at different angles and confirmed their directional emission characteristics.Furthermore,experiments were conducted using fibers of different diameters and hollow glass tubes in combination processing to fabricate peanut-shaped cavities with two lobes of different diameters and single hollow lobes in an asymmetric configuration.The emission characteristics of these cavities were simulated and studied,confirming the universality of this approach.This work proposes a simple method for rapid batch fabrication of WGM peanut-shaped cavities,laying a foundation for research and applications of deformed WGM microcavities.关键词
