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…
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…
