DOI: 10.1364/ome.7.001716
Abstract: We report the simultaneous existence of acoustic and optical asymmetric transmission by combining a periodic array of silicon rods in air with a periodic grating (grating-phoxonic crystals). Theoretically and numerically, we demonstrate that the grating-phoxonic… read more here.
