Abstract

We demonstrate cladding mode assisted supercontinuum generation in a solid core photonic crystal fiber. Although the fiber is commonly considered as endlessly single mode, we show that coupling light into the cladding excites much broader spectrum compared with the situation when only fundamental mode is excited. Comparing experimental data with the results of the modal analysis and the simulations of the pulse propagation in the fiber, we conclude that cladding mode has more favorable dispersion characteristics for the continuum generation. We discuss possible usage of the cladding mode assisted supercontinuum in biosensor applications.
