Abstract

A single-step approach based on heating and pulling single-mode fiber optics via a modulated-arc discharging process is investigated, resulting in microfiber long period gratings (MF-LPGs) structures. In this process, a modulated-arc signal controls the effective axial tension over the fused fiber. Consequently, both microfiber and periodic down-tapers are generated simultaneously through a single-step. This pulse signal period determines the pitch of the induced gratings and adjusts the resonance wavelength of the MF-LPGs. The sample with the diameters of microfiber and tapers equal 30 μm and 15 μm, respectively, provides a high resonance dip up to 26 dB at the wavelength of 1547 nm. The proposed low-cost and fast fabrication technique should be useful for in-line microfiber devices and sensors based on MF-LPGs.
