摘　　要：A Fabry-Perot micro-cavity is fabricated by on-line fiber cutting-welding method.The asymmetrical fiber Fabry-Perot micro-cavity is designed and produced by cutting a standard single-mode fiber and welding the fiber end with the core-offset structure.The length of the Fabry-Perot micro-cavity could be controlled within a certain range of accuracy based on the on-line fiber cutting-welding method.According to this method,a micro-machined Fabry-Perot micro-cavity with a length of about 147μm is achieved and its spectral characteristic is also investigated in our experiment.This proposed method is suitable to produce a micro-fiber-optic structure with improved and controlled precision,which is attractive for the fiber processing field.Moreover,the fabricated Fabry-Perot micro-cavity also has potential application in the microfluidic system and biochemical detection area.
