我们报告说，大于99.8%的光功率转移到回音壁模式实现了在熔融石英微球通过使用双锥形光纤耦合方法。由实验数据推导出了本征腔损耗和锥球耦合系数。结果表明，低的本征损耗和对称的双耦合结构是获得高耦合效率的关键。(C)2000年美国光学学会OCIS代码：230.5750、230.3990、060.1810、230.1150。
We report that greater than 99.8% optical power transfer to whispering-gallery modes was achieved in fused-silica microspheres by use of a dual-tapered-fiber coupling method. The intrinsic cavity loss and the taper-to-sphere coupling coefficient are inferred from the experimental data. It is shown that the low intrinsic loss and the symmetrical dual-coupling structure are crucial for obtaining the high coupling efficiency.
