Abstract

In this paper we demonstrate the fabrication of long-period fiber gratings (LPFGs) based on the photonic crystal fibers (PCFs) with the UV gel infiltrated in all the air holes. The periodic index modulation of the fabricated LPFGs is induced by using the UV light through the amplitude masks with periods of Λ_G = 400 μm, 500 μm, and 600 μm, respectively. By measuring the output spectra of these fabricated LPFGs, we can observe clear notches in the transmission spectra. These notches correspond to the coupling from the core mode to the cladding modes. We also discuss the effect of exposure time of UV light on the grating properties of the fabricated LPFGs.
