Paper Abstract

This paper investigates the transmission spectral properties of tilted long period fiber gratings (TLPFGs) written in fiber tapers with different radiuses. We found that the tilted angle, the radius of fiber and the external refractive index both have influences on the transmission spectral by simulations. With the decrease of the radius of the fiber taper and the increase of refractive index, the resonant wavelength of the tilted LPFG was found to shift towards shorter wavelength. Experimental results show the agreement with the simulation predictions. The TLPFG inscribed in fiber taper also brings the high sensitivity of external refractive index as 566.7 nm/RIU.
