We provide the first experimental evidence of focusing light into subwavelength spots by a 2-dimensional planar photonic structure. When a quasi-periodic array of nanoholes was illuminated with coherent light sources, it created very rich diffraction patterns at different heights to the array. At specific heights, we observed diffraction patterns containing subwavelength spots. The ability to focus light into subwavelength spots is of fundamental importance for applications in a wide range of areas, e.g. microscopy, photo lithography, data storage etc.
