Unusual scaling laws for plasmonic nanolasers beyond the diffraction limit
Nature Communications, 2017 Since the first proposal for plasmonic nanolasers there has been a debate about the limitations on performance posed by the inherent losses in metallic systems.

Polariton lasing in Mie-resonant perovskite nanocavity
Opto-Electronic AdvancesDeeply subwavelength lasers (or nanolasers) are highly demanded for compact on-chip bioimaging and sensing at the nanoscale. One of the main obstacles for the development of single-particle nanolasers with all three dimensions shorter than the emitting ...

Anapole nanolasers for mode-locking and ultrafast pulse generation
Nature Communications, 2017 Here, the authors introduce the concept of nanocscale lasers based on a tightly confined anapole mode. Using first-principle calculations they show that the superposition of internal modes can generate radiation-less states that are scattering free ...

Theory for bowtie plasmonic nanolasers
Optics Express, 2008 We develop a fundamental formulation for electrically-pumped plasmonic semiconductor nanolasers based on a metallic bowtie structure. Because of the negative dielectric constant of the metal at optical frequencies, the effective modal volume of the plasmonic mode can be compressed to the nanometer scale.

Long-term mutual phase locking of picosecond pulse pairs generated by a semiconductor nanowire laser
Nature Communications, 2017 Although nanolasers have been an active field of research for over a decade, mode-locking on the nanoscale has not been achieved yet. Here, Mayeret al.
