Paper Abstract

Microtoroidal is of great use in a wide range of fields including photonics, biosensors, micro-lasers, nonlinear optics, cavity quantum electrodynamics(C-QEDs). In this paper we described ready techniques to fabricate microtoroidals, which included photolithography, isotropic wet etching, and CO2 laser reflow. Two different methods of fabricating biconical optical fiber tapers were also described, which had potential application in near field coupling with microcavity. One of them was to etch a standard single mode fiber(SMF) with buffered hydrofluoric(BHF) acid solution while another was to heat and pull a SMF under control simultaneously. The taper waists as small as 1~3 μm and insertion loss less than 0.46 dB were obtained easily through the two methods. Finally, The values of ΔλFSR (Free Spectrum Range) and Q (Quality Factor) of a fiber-taper and microtoroidal coupled system were measured.
