HETEROSTRUCTURE Russian patent published in 2003 - IPC

FIELD: fiber-optic communication and data transmission systems, high-speed computers, medical instruments. SUBSTANCE: heterostructure for injection lasers is characterized in retrofitted design, comprehensive choice of composition and thickness of its layers ensuring its functioning in narrow transition region for organizing emission of rays from active layer. Heterostructure is distinguished by reduced thickness of emission region, reduced ohmic and thermal resistances, reduced mechanical stresses. EFFECT: simplified design, facilitated manufacture. 13 cl, 4 dwg
