Tunable ultra-narrowband grating filters in thin-film lithium niobate
Alessandro Prencipe, Mohammad Amin Baghban, Katia Gallo
Several applications in modern photonics require compact on-chip optical filters with a tailored spectral response. However, achieving sub-nanometric bandwidths and high extinction…
Charged exciton kinetics in monolayer MoSe near ferroelectric domain walls in periodically poled LiNbO
Pedro Soubelet, Julian Klein, Jakob Wierzbowski +5
Monolayers of semiconducting transition metal dichalcogenides are a strongly emergent platform for exploring quantum phenomena in condensed matter, building novel opto-electronic d…
Golden Ratio entanglement in hexagonally poled nonlinear crystals
Alessandra Gatti, Enrico Brambilla, Katia Gallo +1
This work analyses the quantum state of twin photons and twin beams generated by parametric-down conversion in a hexagonally poled photonic crystal,characterized by the simultaneou…
Purely nonlinear disorder-induced localizations and their parametric amplification
Viola Folli, Katia Gallo, Claudio Conti
We investigate spatial localization in a quadratic nonlinear medium in the presence of randomness. By means of numerical simulations and theoretical analyses we show that, in the d…
Harmonic generation in a two dimensional nonlinear quasicrystal
Neil Broderick, Anna Peacock, Katia Gallo +2
Second harmonic generation in a two dimensional nonlinear quasi-crystal is demonstrated for the first time. Temperature and wavelength tuning of the crystal reveal the uniformity o…
