Fabrication and Optical Characterization of Silica Microspheres

Recently, microspheres have attracted much attention because of their numerous applications as optical microcavities, for example, in microlasers and micro-sensors, using the excitation of whispering gallery modes.In this paper, an economic and simple method(powders floating method) is used to fabricate silica microspheres The sphere diameters are from1 m  to 10 m  by scanning electron microscopy.The optical characterization of the sphere was performed by using the experiment setup of optical characterization
