Tapered micron-sized optical fibers may be important in the future for development of microscale integrated photonic devices. Complex photonic circuits require many devices and a robust technique for interconnection. We demonstrate splicing of four micron diameter step-index air-clad silica microfibers using a CO2 laser. We obtain splice losses lower than 0.3%. Compared with evanescent coupling of microfibers, our splices are more mechanically stable and efficient.
锥形微米级光纤未来对于微尺度集成光子器件的发展可能很重要。复杂的光子电路需要许多器件以及一种强大的互连技术。我们展示了使用二氧化碳激光对四根直径为微米级的阶跃折射率空气包层二氧化硅微光纤进行熔接。我们获得了低于0.3%的熔接损耗。与微光纤的倏逝耦合相比，我们的熔接在机械上更稳定且更高效。
