Time-Resolved dynamics of semiconductor nanolaser via four-wave mixing gating
Federico Monti, Guilhem Madiot, Giuseppe Modica +5
We experimentally demonstrate the direct time-domain characterization of photonic-crystal nanolasers at telecom wavelengths using a nonlinear optical gating technique based on four…
Twisted light from topological chiral exceptional points in a nanolaser array
Kaiwen Ji, Melissa Hedir, Qi Zhong +3
We propose and experimentally demonstrate an orbital angular momentum (OAM) nanolaser array arranged in a ring geometry on an InP-based photonic crystal membrane. The device realiz…
Non-Hermitian zero mode laser in a nanophotonic trimer
Kaiwen Ji, Bruno Garbin, Melissa Hedir +2
Symmetry-protected zero modes in arrays of coupled optical elements have attracted considerable attention because they are expected to be robust against coupling disorders. In the…
Tracking exceptional points above laser threshold
Kaiwen Ji, Qi Zhong, Li Ge +5
Recent studies on non-Hermitian optical systems having exceptional points (EPs) have revealed a host of unique characteristics associated with these singularities, including unidir…
Quantum density matrix theory for a laser without adiabatic elimination of the population inversion: transition to lasing in the class-B limit
Alejandro M. Yacomotti, Zakari Denis, Alberto Biella +1
Despite the enormous technological interest in micro and nanolasers, surprisingly, no class-B quantum density-matrix model is available to date, capable of accurately describing co…
Image classification using collective optical modes of an array of nanolasers
Giulio Tirabassi, Ji Kaiwen, Cristina Masoller +1
Recent advancements in nanolaser design and manufacturing open up unprecedented perspectives in terms of high integration densities and ultra-low power consumption, making these de…
Direct observation of zero modes in a non-Hermitian nanocavity array
Flore Hentinger, Melissa Hedir, Bruno Garbin +5
Zero modes are symmetry protected ones whose energy eigenvalues have zero real parts. In Hermitian arrays, they arise as a consequence of the sublattice symmetry, implying that the…
Experimental study of speckle patterns generated by low-coherence semiconductor laser light
Donatus Halpaap, Mathias Marconi, Romain Hernandez +3
Speckle is a wave interference phenomenon that has been studied in various fields, including optics, hydrodynamics and acoustics. Speckle patterns contain spectral information of t…
Mesoscopic limit cycles in coupled nanolasers
Mathias Marconi, Fabrice Raineri, Ariel Levenson +5
Two coupled semiconductor nanolasers exhibit a mode switching transition, theoretically characterized by limit cycle or mode-beating oscillations. Their decay rate is vanishi…
The driven-dissipative Bose-Hubbard dimer: phase diagram and chaos
A. Giraldo, B. Krauskopf, N. G. R. Broderick +2
We present the phase diagram of the mean-field driven-dissipative Bose-Hubbard dimer model. For a dimer with repulsive on-site interactions () and coherent driving we prove th…
Localization control of few-photon states in parity-symmetric photonic molecules under balanced pumping
C D B Bentley, A Celestino, A M Yacomotti +2
We theoretically investigate the problem of localization control of few-photon states in driven-dissipative parity-symmetric photonic molecules. We show that a quantum feedback loo…
Quench dynamics in strongly coupled laser cavities

Strongly coupled dissipative optical cavities with nonlinear interactions give new opportunities to explore symmetry breaking phenomena and phase transitions, Josephson dynamics an…
Stimulated scattering in strongly coupled nanolasers induced by Rabi oscillations
Mathias Marconi, Julien Javaloyes, Fabrice Raineri +2
Two coupled-cavity systems, or "photonic dimers", are efficient test-beds for both fundamental optics -the realization of quantum correlated states, Josephson physics, and so forth…
Spontaneous mirror-symmetry breaking in a photonic molecule
Philippe Hamel, Samir Haddadi, Fabrice Raineri +5
Multi-cavity photonic systems, known as photonic molecules (PMs), are ideal multi-well potential building blocks for advanced quantum and nonlinear optics. A key phenomenon arising…
