Experimental demonstration of the slow group velocity of light in two-dimensional coupled photonic crystal microcavity arrays
Hatice Altug, Jelena Vuckovic
Abstract
We recently proposed two-dimensional coupled photonic crystal microcavity arrays as a route to achieve a slow-group velocity of light (flat band) in all crystal directions. In this paper we present the first experimental demonstration of such structures with a measured group velocity below 0.008c and discuss the feasibility of applications such as low-threshold photonic crystal lasers with increased output powers, optical delay components and sensors.
