Collective dynamics of evanescently coupled excitable lasers with saturable absorber
Marco Lamperti, Auro Perego
We present a numerical study of the collective dynamics in a population of coupled excitable lasers with saturable absorber. At variance with previous studies where real-valued (lo…
Probing one-dimensional topological phases in waveguide lattices with broken chiral symmetry
Stefano Longhi
One-dimensional lattices with chiral symmetry are known to possess quantized Zak phase and nontrivial topological phases. Here it is shown that quantized Zak phase and nontrivial e…
Photonic Flatband Laser
Stefano Longhi
Flatband photonic lattices, i.e. arrays of waveguides or resonators displaying a flat Bloch band, offer new routes for light trapping and distortion-free imaging. Here it is shown…
An energy window study of light transmission-disorder relationship in 1D photonic structures
Michele Bellingeri, Davide Cassi, Francesco Scotognella
While the light transmission of photonic crystals is characterized by the photonic band gap, the one of disordered photonic structures is typified by a multiplicity of transmission…
Fundamental limits on the losses of phase and amplitude optical actuators
Simone Zanotto, Francesco Morichetti, Andrea Melloni
Amplitude and phase are the basic properties of every wave phenomena; as long as optical waves are concerned, the ability to act on these variables is at the root of a wealth of sw…
Metasurface reconfiguration through lithium ion intercalation in a transition metal oxide
Simone Zanotto, Alessandra Blancato, Annika Buchheit +4
In the latest years the optical engineer's toolbox has welcomed a new concept, the metasurface. In a metasurface, properly tailored material inclusions are able to reshape the elec…
symmetry and anti-symmetry by anti-Hermitian wave coupling and nonlinear optical interactions
Stefano Longhi
Light propagation in systems with anti-Hermitian coupling, described by a spinor-like wave equation, provides a general route for the observation of anti parity-time ($\mathcal{PT}…
Femtosecond laser written diamond waveguides - a step towards integrated photonics in the far infrared
Vibhav Bharadwaj, Yuchen Wang, Toney Teddy Fernandez +3
A first demonstration and complete characterization of mid-infrared waveguides in diamond are reported in detail. Waveguides were designed for 2.4 um and 8.6 um waveguiding, with t…
Exceptional points and photonic catastrophe
Stefano Longhi
Exceptional points (EPs) with a global collapse of pairs of eigenfunctions are shown to arise in two locally-coupled and spatially-extended optical structures with balanced gain an…
Presence of temporal dynamical instabilities in topological insulator lasers
S. Longhi, Y. Kominis, V. Kovanis
Topological insulator lasers are a newly introduced kind of lasers in which light snakes around a cavity without scattering. Like for an electron current in a topological insulator…
One-dimensional disordered photonic structures with two or more materials
Alessandro Chiasera, Luigino Criante, Stefano Varas +9
Here we would like to discuss the light transmission modulation by periodic and disordered one dimensional (1D) photonic structures. In particular, we will present some theoretical…
Coherent virtual absorption for discretized light
Stefano Longhi
Coherent virtual absorption (CVA) is a recently-introduced phenomenon for which exponentially growing waves incident onto a conservative optical medium are neither reflected nor tr…
Attosecond electronic recollision as field detector
P. Carpeggiani, M. Reduzzi, A. Comby +10
We demonstrate the complete reconstruction of the electric field of visible-infrared pulses with energy as low as a few tens of nanojoules. The technique allows for the reconstruct…
Mitigation of dynamical instabilities in laser arrays via non-Hermitian coupling
S. Longhi, L. Feng
Arrays of coupled semiconductor lasers are systems possessing complex dynamical behavior that are of major interest in photonics and laser science. Dynamical instabilities, arising…
Non-Hermitian gauged topological laser arrays
Stefano Longhi
Stable and phase-locked emission in an extended topological supermode of coupled laser arrays, based on concepts of non-Hermitian and topological photonics, is theoretically sugges…
