Phys. Rev. B 74, 073401 (2006) [4 pages]Optical absorption by atomically doped carbon nanotubesReceived 16 May 2006; published 1 August 2006 We analyze optical absorption by atomically doped carbon nanotubes with a special focus on the frequency range close to the atomic transition frequency. We derive the optical absorbtion line-shape function and, having analyzed particular achiral nanotubes of different diameters, predict the effect of absorbtion line splitting due to strong atom-vacuum-field coupling in small-diameter nanotubes. We expect this effect to stimulate relevant experimental efforts and thus to open a path to new device applications of atomically doped carbon nanotubes in modern nanotechnologies. © 2006 The American Physical Society URL:
