In this paper we report experimental results concerning electrical tuning of a long period grating (LPFG) using as its external layer a liquid crystal (LC). The studied LPFG was fabricated by using UV irradiation in a boron co-doped fiber (PS1250/1500, manufactured by Fibercore). As an LC we used the 1550 nematic LC mixture. Electrical tuning of the LPFG transmission spectrum is achieved by varying the boundary condition of the LC layer. As a result, a blue shift of the attenuation band up to 6.2nm was obtained.
