DREIDIMENSIONALER PHOTONENKRISTALL UND OPTISCHE BAUTEILE MIT EINEM SOLCHEN

摘要

A three-dimensional photonic crystal has periodic-refractive-index structures including a first layer (110) having a periodic structure based on a first rectangular lattice having a period of A along a first axis and a period of B along a second axis orthogonal to the first axis in the plane direction, a second layer (120) having a periodic structure disposed at a position shifted by +3B/8 along the second axis with respect to the position of the first rectangular lattice, a third layer (130) having a periodic structure disposed at a position shifted by A/2 along the first axis and B/2 along the second axis with respect to the position of the periodic structure in the first layer, and a fourth layer (140) having a periodic structure disposed at the same position as the periodic structure in the second layer.
