  • Abstract
    We demonstrate up-converted light emission from an asymmetric double quantum well (QW). Carriers in the wide QW, which are photogenerated by a long wavelength light, are transferred and collected into the adjacent narrow quantum well by using Γ-X-Γ electron transfer and simultaneous hole tunneling, thus generating short wavelength light emission.
