A NUMERICAL ANALYSIS OF AN ATHERMAL PACKAGING FOR A PHOTONIC CRYSTAL FIBER BASED LONG PERIOD GRATING TUNABLE FILTER
In this paper, a quantitative analysis of an athermal design for a filter based on the combination of a photonic crystal fiber (PCF) long period grating (LPG) with a bimetal strip structure is presented. The single resonant band LPG is manufactured by arc-fusing method with 55 periods which produce the largest resonant spectrum. The temperature dependent effective index was obtained from both experimental and computational results. Although the basic operational principle and implementation of this LPG filter have been previously reported, this paper is focused on the quantitative analysis of the athermal design, which may significantly enhance the practicability of the PCF LPG filter. A commercial available finite element program ANSYS was implemented to analyze the tunable feature of bimetal structure.
