Polaritons are quasiparticles that form in semiconductors when an elementary excitation
such as an exciton or a phonon interacts sufficiently strongly with light. In particular, exciton …

Resonance interaction between a molecular transition and a confined electromagnetic field
can reach the coupling regime where coherent exchange of energy between light and …

The strong coupling of photons and matter in semiconductor nanocavities has been a test
bed for cavity quantum electrodynamics,(QED). Vacuum Rabi oscillation,,,,—the coherent …

The influence of pure dephasing on the dynamics of the coupling between a two-level atom
and a cavity mode is systematically addressed. We have derived an effective atom-cavity …

The progression of carrier confinement from quantum wells to quantum dots has received
considerable interests because of the potential to improve the semiconductor laser …

Micro‐and nanolasers are emerging optoelectronic components with many properties still to
be explored and understood. On the one hand, they make it possible to address …

The directed growth of III–V nanopillars is used to demonstrate bottom-up photonic crystal
lasers. Simultaneous formation of both the photonic band gap and active gain region is …

Recent theoretical and experimental progress on nanolasers is reviewed with a focus on the
emission properties of devices operating with a few or even an individual semiconductor …

Thresholdless lasing is an outstanding challenge in laser science and is achievable only in
devices having near unity quantum efficiency even when not lasing. Such lasers are …

The lasing behavior of one dimensional GaAs nanobeam cavities with embedded InAs
quantum dots is studied at room temperature. Lasing is observed throughout the quantum …
