Short wavelength light emitting element

摘要: PROBLEM TO BE SOLVED: To enable effectively generating a light of high output power, by using substrate cubic system, making an active layer In x3 Ga 1-x3 N 1-y3 As y3 quantum well, and constituting clad optical waveguide GaAlNAs system lattice-matching with the or GaAlNa/GaNAs superlatticle. SOLUTION: A short wavelength emitting element has N-Ga 1-x1 Al x1 1-y1 y1 2, I-Ga 1-x2 x2 1-y2 y2 3, I-In well 4, P 5, P-Ga 6 P-GaN 1-y5 y5 contact 7, on N-GaN 1 system. The layers 5 lattice-match 1. result, generation current which is to be caused leakage carrier restrained, increase temperature can reduced at time driving current, reliability improved.
