Spaserin Quantum Regime

Nanoplasmonicsdeals with collective electron dynamics on the surface of metal nanostructures, which arises due to excitations called surface plasmons. Nanoplasmonicshas numerous applications in science, technology, biomedicine, environmental monitoring, and defense. Until recently, all the effects, elements, and devices in nanoplasmonicshave been passive: they use external optical energy, always losing a fraction of it to heat and leakage radiation. An active device generating energy directly on the nanoscale has been spaser(surface plasmonamplification by stimulated emission of radiation). The spaserhave been introduced theoretically and discovered experimentally. We briefly consider quantum theory and latest results on spaseras an ultrafast quantum generator and amplifier of nanoplasmonicfields, ultrabrightnanolabel, and highly-efficient nanosensor. We present latest original results: electrical nanospaserin the extreme quantum regime and graphene nanospaser.
