Abstract
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.
