Nonlinear Self-Action across Temporal Regimes in Resonant Dielectric Metasurfaces
Alfonso Nardi, Sonia Freddi, Michael Scalora +8
Quasi-bound states in the continuum (qBICs) enable exceptional field confinement, strongly reducing the pump intensity threshold for nonlinear light-matter interaction in dielectri…
Efficient photon-pair emission from a nanostructured resonator and its theoretical description
Michael Poloczek, Alberto Paniate, Attilio Zilli +12
Spontaneous parametric down-conversion (SPDC) in subwavelength nanostructures is a promising source of quantum light, owing to its multifunctionality and ability to generate comple…
Polarization-Multiplexed Bloch Surface Wave Sensing of Single-Strand DNA Growth
Jonathan Barolak, Erika Mogni, Giovanni Pellegrini +8
