発明の名称 (英語) TWO-DIMENSIONAL PHOTONIC CRYSTAL PLANE EMISSION LASER
発明の概要(英語) A two-dimensional photonic crystal plane emission laser 10 is provided with: an active layer 11; and a photonic crystal layer 12 including a two-dimensional photonic crystal light-amplifying portion 123 and a two-dimensional photonic crystal light-reflecting portion 125. The two-dimensional photonic crystal light-amplifying portion 123 is a first two-dimensional photonic crystal region provided on a plate-like base material 121 disposed on one side of the active layer 11, and has an amplifying portion photonic band gap 15 that is a photonic band gap formed between two photonic bands having band ends at predetermined points in an inverse lattice space. The two-dimensional photonic crystal light-reflecting portion 125 is a second two-dimensional photonic crystal region provided around the two-dimensional photonic crystal light-amplifying portion 123, and has a reflecting portion photonic band gap 16 which is a photonic band gap formed between two photonic bands having band ends at the predetermined points in the inverse lattice space. The amplifying portion photonic band gap 15 and the reflecting portion photonic band gap 16 have partly overlapping and yet different energy ranges.
