在一个坚固的瓶形微谐振器中，用一小段光纤直接制作了一个球形回音壁模和瓶模的选择性激发。利用锥形光纤在其轴向沿着不同点激励渐逝瓶型微谐振器，得到了长腔瓶模的特征谐振谱。与裸光纤圆柱形谐振器相比，瓶形微谐振器的Q值提高了35倍。(C)2009年美国光学学会
Selective excitation of spheroidal whispering gallery modes and bottle modes in a robust bottle microresonator fabricated straightforwardly from a short section of optical fiber is demonstrated. Characteristic resonance spectra of long-cavity bottle modes were obtained by using a tapered fiber to excite evanescently bottle microresonator at different points along its axis. Compared to bare-fiber cylindrical resonators, the bottle microresonator results in a 35x increase of the observed Q factor. (C) 2009 Optical Society of America
