Fabrication of Micro/Nano optical Fiber by Electrospinning Direct-writing

Abstract

Because of the excellent performance, Micro/Nano optical fiber has been more and more widely applied in passive photonic devices, micro-optical sensors, field of atomic manipulation, etc. Currently the main manufacturing mode of Micro/Nano optical fiber is the stretching method which is susceptible to air impact, vulnerable to contaminant and has poor reproducibility. In order to solve these problems, the fabrication of the Micro/Nano optical fiber by electrospinning direct-writing is researched in this article. The experimental platform is set up after the scheme of electrospinning direct-writing is designed. A series of comparative experiments are carried out with changing three experimental variables. The PMMA Micro/Nano optical fiber of controllable diameter is fabricated by regulating the distance between the sprinkler head and collecting plate, flow rate and concentration of PMMA solution. The testing results indicate that the light transmission power loss rate of the PMMA Micro/Nano optical fiberis 0.41dB/mmexcited by a 633-nm-wavelength light. The problem is expected to be solved by further optimization of the experimental process and parameters.
