Plasmonic nanolasers have excellent potential for ultrafast modulation due to their ability to accelerate spontaneous emission and increase the modulation bandwidth. Critical metrics of the nanolaser dynamics include photon lifetime, spontaneous emission rate, and polarization lifetime. However, these processes have significantly different lifetimes, which presents a challenge for modeling. Classical rate equations fail to predict the modulation behavior accurately. In this talk, we cover some history of the numerical modeling of nanoscale lasers and discuss our efforts on developing accurate computational approaches to describing modulated plasmonic nanolasers. We also highlight the regimes where multi-scale methods can still be used efficiently.
