Large static tuning of narrow-beam terahertz plasmonic lasers operating at 78 K
Chongzhao Wu, Yuan Jin, John L. Reno +1
A new tuning mechanism is demonstrated for single-mode metal-clad plasmonic lasers, in which refractive-index of the laser's surrounding medium affects the resonant-cavity mode in…
Terahertz plasmonic laser radiating in an ultra-narrow beam
Chongzhao Wu, Sudeep Khanal, John L. Reno +1
Plasmonic lasers (spasers) generate coherent surface-plasmon-polaritons (SPPs) and could be realized at subwavelength dimensions in metallic cavities for applications in nanoscale…
Thresholdless Coherent Light Scattering from Subband-polaritons in a Strongly-Coupled Microcavity
Johannes Gambari, Antonio I Fernandez-Dominguez, Stefan A Maier +5
We study a "strongly-coupled" (SC) polariton system formed between the atom-like intersubband transitions in a semiconductor nanostructure and the THz optical modes that are locali…
Coherence of resonant-tunneling transport in terahertz quantum-cascade lasers
Sushil Kumar, Qing Hu
We develop simple density-matrix models to describe the role of coherence in resonant-tunneling (RT) transport of quantum-cascade lasers (QCLs). Specifically, we investigate the ef…
