Sub-minute Quantum Ghost Imaging in the infrared enabled by a "looking back" SPAD array
Valerio Flavio Gili, Dupish Dupish, Andres Vega +6
Quantum Ghost Imaging (QGI) is an intriguing imaging protocol that exploits photon-pair correlations stemming from spontaneous parametric down-conversion (SPDC). QGI retrieves imag…
Tailoring Nanowire Lasing Modes via Coupling to Metal Gratings
Francesco Vitale, Daniel Repp, Thomas Siefke +4
Tailoring the emission of plasmonic nanowire-based lasers represents one of the major challenges in the field of nanoplasmonics, given the envisaged integration of such devices int…
Lasing modes in ZnO nanowires coupled to planar metals
Daniel Repp, Angela Barreda, Francesco Vitale +4
Semiconductor nanowire lasers can be subject to modifications of their lasing threshold resulting from a variation of their environment. A promising choice is to use metallic subst…
Meta-Optics with Lithium Niobate
Anna Fedotova, Luca Carletti, Attilio Zilli +8
The rapid development of metasurfaces - 2D ensembles of engineered nanostructures - is presently fostering a steady drive towards the miniaturization of many optical functionalitie…
Nonlinear quantum spectroscopy with Parity-Time symmetric integrated circuits
Pawan Kumar, Sina Saravi, Thomas Pertsch +2
We propose a novel quantum nonlinear interferometer design that incorporates a passive PT symmetric coupler sandwiched between two nonlinear sections where signal-idler photon pair…
Group index matched frequency conversion in lithium niobate on insulator waveguides
Pawan Kumar, Mohammadreza Younesi, Sina Saravi +2
Sources of spectrally engineered photonic states are a key resource in several quantum technologies. Of particular importance are the so-called factorizable biphoton states which p…
