Stabilizing nanolasers via polarization lifetime tuning
Scientific Reports, 2021 We investigate the emission dynamics of mutually coupled nanolasers and predict ways to optimize their stability, i.e., maximize their locking range.

Plasmonic Bowtie Nanolaser Arrays [PDF]
Nano Letters, 2012 Plasmonic lasers exploit strong electromagnetic field confinement at dimensions well below the diffraction limit. However, lasing from an electromagnetic hot spot supported by discrete, coupled metal nanoparticles (NPs) has not been explicitly demonstrated to date. We present a new design for a room-temperature nanolaser based on three-dimensional (3D)

“Amplified Spontaneous Emission” in Micro- and Nanolasers
Atoms, 2021 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 ...

Tunable Unidirectional Guided Resonances via Multi‐Singularity Interactions in Momentum Space
Nanophotonics, Volume 15, Issue 15, 13 August 2026.C points can intrinsically coexist around symmetry‐protected BICs without symmetry reduction. Symmetry breaking splits SP‐BICs into new C points that interact with intrinsic ones, forming perfect UGRs at distinct k points with tunable topological charges.

Plasmonic crystal defect nanolaser
Optics Express, 2011 Surface plasmons are widely interesting due to their ability to probe nanoscale dimensions. To create coherent plasmons, we demonstrate a nanolaser based on a plasmonic bandgap defect state inside a surface plasmonic crystal. A one-dimensional semiconductor-based plasmonic crystal is engineered to have stopbands in which surface plasmons are prohibited

Self-Assembled Dipole Nanolasers
, 2016 Visible light excitation of silver nanoparticles in the presence of polymerizable monomers and selected dyes triggers the self-assembly of nanolasers in a synthetically simple process. The new nanolasers incorporate a thin, fully organic gain medium that

Mesoscopic Limit Cycles in Coupled Nanolasers [PDF]
, 2020 International audienceTwo coupled semiconductor nanolasers exhibit a mode switching transition, theoretically characterized by limit cycle-or mode-beating-oscillations. Their decay rate is vanishingly small in the thermodynamic limit, i.e.
