文摘
We elaborate InP1?xAsx quantum dots embedded in InP nanowires by Au-catalyzed molecular beam epitaxy. Each nanowire contains a quantum dot well positioned on its axis and presenting a cylindrical geometry with sharp interfaces. The quantum dot emission wavelength can be tuned in the optical fiber transmission range and the final shape of the nanowire is tailored for efficient wave-guiding and light extraction. These objects, obtained in a single growth run, open a new route to the fabrication of efficient single photon sources.
