Abstract
Nonlinear propagation of femtosecond laser pulses in dual core photonic crystal fiber was studied from the point of view of spectral and spatial redistribution of the interacting radiation. The fiber had quadratic microstructure and was made of multicomponent glass. The experiments were performed in the anomalous dispersion region of the fiber. Excitation pulses with central wavelength 1300 nm were applied. The experimental apparatus enabled separate excitation and separate spectral registration of the two fiber cores. According to the dependence of the output spectra on the input pulse energy and the profile of the spectra indicates solitonic propagation in the double core structure. Moreover, possibility to switch the spectral intensity between the two output channels by simple change of the input pulse energy or polarization direction were showed in spectral regions of fiber communication systems.
