In this work, we demonstrate highly efficient anti-Stokes signal generation inside an irregular multicore microstructure fiber, using unamplified femtosecond laser pulses. For this special type of fiber, there are randomly distributed cores with a diameter ranging from 0.6 to 1.5 μm. We have observed a large ratio of the amplitude of the anti-Stokes wave to that of the pump wave in the output spectrum. Our simulation results indicate that the features of the two zero-dispersion wavelengths of the fiber are responsible for meeting the phase-matching condition of four-wave mixing, which produces the observed large anti-Stokes wave. © 2005 Wiley Periodicals, Inc.
