<Zhores Alferov> developed <double heterostructure> <semiconductor> devices that confine carriers in a narrow active region. Different <band gaps> inhibit carrier escape, while refractive-index contrast can guide the optical field through the same region. Bringing carriers and <light> together increases useful gain and reduces the current needed for <laser> operation. His account connects the heterostructure concept with practical <semiconductor> lasers and other electronic and optoelectronic devices.<Nobel Lecture: The double heterostructure concept and its applications in physics, electronics, and technology by Zhores Ivanovich Alferov>[Reviews of Modern Physics 73, 767 (2001), carrier/optical confinement and device applications]{ref}
