Abstract
Using soft lithography technology, the 2D photonic crystal superprism structures with a triangle array of air holes on the polymer slab were designed, simulated and fabricated successfully. The profile of the molded structures with 450nm in diameter and 900nm in lattice constant was obtained and observed by SEM. By means of optical experiment and measurement, when the input incident angle varied from 15° to 11°, we observed the beam propagation angle change from positive to negative and the superprism effect was demonstrated effectively at near-infrared wavelength 1550nm.
