Abstract

We demonstrated experimentally the fabrication of tilted long-period fiber gratings (TLPFGs) with by CO₂ laser. The writing efficiency can be dramatically improved by increasing the tilt angle. We fabricated the non-titled long-period fiber gratings with equivalent grating period in the same fiber. The experimental results show that the transmission spectra of non-titled equivalent LPFGs are similar with that of the TLPFGs. The TLPFG is found to have higher refractive index sensitivity than the corresponding equivalent LPFG.
