Ultrafast and quantum dynamics of plasmonic nanolasing

摘要

Lasers have in recent years become smaller and smaller, reaching with the demonstration of plasmonic nanolasing, scales much smaller than the wavelength of the light they emit [1, 2]. Such plasmonic nanolasers employ plasmonic resonances for feedback, allowing them to concentrate light into mode volumes that are no longer limited by diffraction. But it does not stop there. Next to this dramatic reduction in cavity size, plasmonic lasers also unlock a number of fundamentally new lasing characteristics and phenomena.
