Phys. Rev. A 71, 063812 (2005) [7 pages]Dipole nanolaserSee Also: Erratum Received 6 December 2004; published 17 June 2005 A “dipole” laser is proposed consisting of a nanoparticle and a two-level system with population inversion. If the threshold conditions are fulfilled, the dipole interaction between the two-level system and the nanoparticle leads to coherent oscillations in the polarization of the particles, even in the absence of an external electromagnetic field. The emitted radiation has a dipolar distribution. It does not need an optical cavity, and has a very small volume, ∼0.1 μm3, which can be important for applications in microelectronics. Estimates of the threshold conditions are carried out for a dipole laser composed of a quantum dot and a silver nanoparticle. © 2005 The American Physical Society URL:
