Abstract
A multi-channel tunable mechanically induced long-period fiber gratings (LPFGs) scheme is presented, which can induce several LPFGs with different resonance wavelengths simultaneously. LPFGs spectra characteristics are simulated to find the influence of these parameters such as grating length, tilt angle and the pressure on the fiber. The simulation results show that the transmission loss peak mainly depends on both the grating length and the pressure, while tilt angle factor dominates the resonant wavelength. The infuence of the pressure and tilt angles on the transmission spectra is experimentally studied. This multi-channel LPFGs module will have great potential applications in the fiber sensing field and flexible filter design region.
