Abstract
AbstractWe theoretically demonstrate the possibility of low‐energy surface plasmon amplification by optically excited excitons in small‐diameter carbon nanotubes. The stimulated character of such an energy transfer causes the buildup of the macroscopic population numbers of coherent localized surface plasmons. As a consequence, high‐intensity coherent optical‐frequency fields are created at nanoscale throughout the nanotube surface. These strong local fields can be used in a variety of new optoelectronic applications of carbon nanotubes, including near‐field nonlinear‐optical probing and sensing, optical switching, enhanced electromagnetic absorption, and materials nanoscale modification.
