Abstract

Presented work is dedicated to analysis of nonlinear effects in dual core photonic crystal fiber. Both theoretical and experimental approaches are used. Theoretical analysis includes determination of dispersion and coupling curves. Simulation of nonlinear propagation is based on coupled generalized nonlinear Schrödinger equations. Modified numerical model utilizing split-step Fourier method was adapted for dual core fibers. In theoretical part possibility to use dual core fiber as supercontinuum source or nonlinear coupler is analyzed. Possibility to influence coupling efficiency and coupling length by intensity was shown in order to propose utilization of dual core fiber as nonlinear coupler. Experimental analysis was performed with femtosecond laser system in near IR region. Investigation included different input settings such as polarization, intensity, selective input coupling into each core and selective detection of spectra from each core. Theoretical and experimental spectra are compared and analyzed.
