Dissipative Josephson effect in coupled nanolasers
Josephson effects are commonly studied in quantum systems in which dissipation or noise can be neglected or do not play a crucial role. In contrast, here we discuss a setup where dissipative interactions do amplify a photonic Josephson current, opening a

“Amplified Spontaneous Emission” in Micro- and Nanolasers
Amplified Spontaneous Emission is ubiquitous in systems with optical gain and is responsible for many opportunities and shortcomings. Its role in the progression from the simplest form of thermal radiation (single emitter spontaneous emission) all the ...

Dipole‐Quadrupole Model and Multipole Analysis of Resonant Membrane Metasurfaces
Membrane metasurfaces, arrays of holes in a dielectric membrane, are appealing because they require no substrate and allow access to resonant near‐fields. However, developing a comprehensive theoretical description for them remains challenging. We introduce a semi‐analytical dipole‐quadrupole approach to analyze their resonant spectra at arbitrary ...

Hybrid gap plasmon GaAs nanolasers [PDF]
Compact semiconductor lasers with sub-wavelength-scale dimensions rely heavily on materials with low surface recombination due to the large surface area to volume ratios of their nano-cavities.

A "dipole" laser is proposed consisting of a nanoparticle and a two-level system with population inversion. If the threshold conditions are fulfilled, the dipole interaction between the two-level system and the nanoparticle leads to coherent oscillations in the polarization of the particles, even in the absence of an external electromagnetic field. The

Stabilizing nanolasers via polarization lifetime tuning
We investigate the emission dynamics of mutually coupled nanolasers and predict ways to optimize their stability, i.e., maximize their locking range.

Theory for bowtie plasmonic nanolasers
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.

Harnessing Interfacial Field Localization in Hexagonal GaP Mie Resonators
Сharacterization of Mie modes in self‐assembled GaP nanowires grown by MBE in vertical and horizontal configurations. The hexagonal cross‐section suppresses higher‐order modes while preserving dominant low‐order modes with spectral shifts. Simulations and dark‐field spectroscopy confirm the diameter‐dependent tunability.

Ten years of spasers and plasmonic nanolasers [PDF]
Ten years ago, three teams experimentally demonstrated the first spasers, or plasmonic nanolasers, after the spaser concept was first proposed theoretically in 2003.
