“…The accelerated spontaneous emission into lasing modes enables nanolasers to have ultrafast responses 106 . Theoretical studies and numerical simulations have shown that nanolasers can be modulated at 100s GHz or even up to THz [107][108][109][110][111][112][113] . Recently, a nanolaser emitting sub-picosecond pulses has been experimentally demonstrated 85 .…”

“…This, in turn, modifies the lasing threshold for a particular mode. An increased β-factor further accelerates the temporal response under direct laser modulation 69,82,[107][108][109][110][111][112][113] . Accessing high Purcell factors through high-cavity quality is not valid when the cavity resonance is narrower than the inhomogeneously broadened emission linewidth.…”

“…One of the related issues with short carrier lifetimes is the validity of the rate equation approximations 113 . The complete set of Maxwell-Bloch equations describing a semiconductor laser includes coupled rate equations for photons and the population as well as the medium polarization equation.…”

“…Therefore, the ultrafast modulation of plasmonic nanolasers, in general, cannot be analyzed based on the conventional rate equations alone. The validity of the rate equations was recently studied 113 together with an analysis of the modulation of plasmonic nanolasers using a more complete set of equations beyond the rate equation approximation. Although there have been extensive theoretical studies, a systematic experimental investigation of plasmonic nanolasers is still lacking, with only a limited number of papers having been published on this topic.…”

Ten years ago, three teams experimentally demonstrated the first spasers, or plasmonic nanolasers, after the spaser concept was first proposed theoretically in 2003. An overview of the significant progress achieved over the last 10 years is presented here, together with the original context of and motivations for this research. After a general introduction, we first summarize the fundamental properties of spasers and discuss the major motivations that led to the first demonstrations of spasers and nanolasers. This is followed by an overview of crucial technological progress, including lasing threshold reduction, dynamic modulation, room-temperature operation, electrical injection, the control and improvement of spasers, the array operation of spasers, and selected applications of single-particle spasers. Research prospects are presented in relation to several directions of development, including further miniaturization, the relationship with Bose-Einstein condensation, novel spaser-based interconnects, and other features of spasers and plasmonic lasers that have yet to be realized or challenges that are still to be overcome.

“…The remaining part of the total Purcell factor tot m () FF  corresponds to the change of energy decay rate to all other modes. Thus, in order to make the laser threshold smaller, one has to increase  by enhancement of the mode Purcell factor m F as much as possible, simultaneously reducing tot m () FF  .Rate equations.Taking into account all the processes of pumping, energy transfer, radiation and dissipation, the dynamics of the coupled gain-resonator system can be described (weak-coupling regime) by so-called rate equations[149]-[151]:…”

Recent progress in nanofabrication has led to tremendous technological developments in nanophotonics, which rely on the interaction of light with nanostructured matter. Nanophotonics has experienced a large surge of interest in recent years, from basic research to applied technology.The increased importance of extremely low-energy data processing at ultra-fast speeds has been encouraging the use of light for signal transport and processing. Energy demands and interaction time scales become smaller with the physical size of the nanostructures, hence nanophotonics opens the opportunity of integrating a large number of devices that can generate, control, modulate, sense and process light signals at ultrafast speeds and below femtojoule/bit energy levels.However, losses and diffraction pose fundamental challenges to the fundamental ability of nanophotonic structures to confine light efficiently in smaller and smaller volumes. In this framework, active nanophotonics, which combines the latest advances in nanotechnology with gain materials, has become in recent years a vital area of optics research, both from the physics, material science, and engineering standpoint. In this paper, we review recent efforts in enabling active nanodevices for lasing and optical sources, loss compensation, and to realize new optical functionalities, like -symmetry, exceptional points and nontrivial lasing based on suitably engineered distributions of gain and loss in nanostructures.
