Abstract
We present experimental control of the acceleration direction of Airy beams generated by nonlinear threewave mixing processes in an asymmetrically poled nonlinear photonic crystal. Changing the crystal temperature enabled us to switch the phase matching condition between second-harmonic generation and difference-frequency generation in the same nonlinear crystal and thereby to change the acceleration direction and the wavelength of the output Airy beam. All-optical control of the acceleration direction can be also realized at a fixed crystal temperature by using a tunable pump source and selecting the proper crystal poling period.
