Abstract
Local light intensity at a defect in a photonic crystal structure is g reatly enhanced from the input light intensity by the existence of the photonic state localized around the defect. Enhancement of effective optical nonlinearity of photonic crystal structures with a defect whic h has optical nonlinearity was considered theoretically, and studied e xperimentally. In experiment, intensity dependence of the transmittanc e was measured, and reduction of the effective saturation intensity by factor of 20 was observed.
