Multiphysics Analysis Of An All-photonic Crystal Fiber Device

Abstract

A multiphysics analysis of an all-fiber device based on photonic crystal fiber is reported. The device is a solid-core high-birefringent photonic crystal fiber with two integrated electrodes at the cladding region. A finite clement code was used to perform an electro-thermo-mechanical-opto coupled analysis. The device operates applying an electrical current on the integrated electrodes that causes heating by Joule effect and, consequently, its thermal expansion which squeezes the fiber microstructure. The results demonstrate the possibility of actively tuning the modal birefringence with electrical current. ©2009IEEE.800803Chesini, G., Cristiano, M., Cordeiro, B., Christiano, J., De Matos, S., Fokine, M., Isabel, C., Knight, J.C., All-fiber devices based on photonic crystal fibers with integrated electrodes (2009) Optics Express, 17 (3), pp. 1660-1665. , FebruaryFokine, M., Nilsson, L.E., Claesson, A., Berlemont, D., Kjellberg, L., Krummenacher, L., Margulis, W., Integrated fiber Mach-Zehnder interferometer for electro-optic switching (2002) Opt.
