Abstract

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 × 108 was obtained for a toroidal microresonator with 40 mm diameter.
