摘要：
We report simple, reproducible methods of fabricating tapered optical fibers with subwavelength diameter and silica microtoroidal resonators, both operating at a wavelength of 850 nm. The transmission loss of tapered fibers was reduced to 0.03 dB by controlling the adiabaticity of the tapered region. The Q factor of 3 x 10(8) was obtained for a toroidal microresonator with 40 mu m diameter. (C) 2010 The Japan Society of Applied Physics
