Abstract

Preparation, control and measurement of optical vortices is increasingly important as they play an essential role in new applications to fundamental science and optical technologies. Spatial light modulation is the main approach behind the control strategies. Here, we demonstrate the modulation of light by light to observe the triangular-lattice pattern resulting from the spatial cross modulation between an optical vortex and a triangular shaped beam undergoing parametric interaction. Both up- and down-conversion processes are investigated.
