PROBLEM TO BE SOLVED: To provide a novel structure capable of exhibiting a reflection function based on Guided Resonance even if not obtaining sufficient difference in refractive index between a photonic crystal layer and a low refractive index layer adjacent thereto, and to provide a surface-emitting laser employing the same. SOLUTION: The structure includes a photonic crystal layer including a first member 1000 having a first refractive index and having a surface with a plurality of holes periodically arranged therein, and a low refractive index layer 1020 adjacent to the photonic crystal layer and having a second refractive index lower than the first refractive index. The relative refractive index difference between the first refractive index and the second refractive index is not more than 0.10. Third members 1015 having a third refractive index higher than 1.0 are disposed inside the holes. COPYRIGHT: (C)2008,JPO&INPIT
