Nonlinear adiabatic optical isolator
Andon Rangelov, Stefano Longhi
We theoretically propose a method for optical isolation based on adiabatic nonlinear sum frequency generation in a chirped quasi-phase-matching crystal with strong absorption at th…
Magneto-optical switching in microcavities based on a TGG defect sandwiched between periodic and disordered one-dimensional photonic structures
Ilka Kriegel, Francesco Scotognella
The employment of magneto-optical materials to fabricate photonic crystals gives the unique opportunity to achieve optical tuning by applying a magnetic field. In this study we hav…
Chiral Surface Waves for Enhanced Circular Dichroism
Giovanni Pellegrini, Marco Finazzi, Michele Celebrano +2
We present a novel chiral sensing platform that combines a one-dimensional photonic crystal design with a birefringent surface defect. The platform sustains simultaneous transverse…
Correlated spontaneous emission of fluorescent emitters mediated by single plasmons
Dorian Bouchet, Emmanuel Lhuillier, Sandrine Ithurria +5
Manipulating the spontaneous emission of a fluorescent emitter can be achieved by placing the emitter in a nanostructured environment. A privileged spot is occupied by plasmonic st…
-symmetric mode-locking
Stefano Longhi
Parity-time () symmetry is one of the most important accomplishments in optics over the past decade. Here the concept of mode-locking of a laser is int…
Projecting light beams with 3D waveguide arrays
Andrea Crespi, Francesca Bragheri
Free-space light beams with complex intensity patterns, or non-trivial phase structure, are demanded in diverse fields, ranging from classical and quantum optical communications, t…
Bidirectional invisibility in Kramers-Kronig optical media
Stefano Longhi
A broad class of planar dielectric media with complex permittivity profiles that are fully invisible, for both left and right incidence sides, is introduced. Such optical media are…
Black Phosphorus based One-dimensional Photonic Crystals and Microcavities
I. Kriegel, S. Toffanin, F. Scotognella
The latest achievements in the fabrication of black phosphorus thin layers, towards the technological breakthrough of a phosphorene atomically thin layer, are paving the way for a…
Coherent perfect absorption in photonic structures
Lorenzo Baldacci, Simone Zanotto, Alessandro Tredicucci
The ability to drive a system with an external input is a fundamental aspect of light-matter interaction. The coherent perfect absorption (CPA) phenomenon extends to the general mu…
A Single-Photon Imager Based on Microwave Plasmonic Superconducting Nanowire
Qing-Yuan Zhao, Di Zhu, Niccolò Calandri +6
Detecting spatial and temporal information of individual photons by using single-photon-detector (SPD) arrays is critical to applications in spectroscopy, communication, biological…
Enhancement and Inhibition of Spontaneous Photon Emission by Resonant Silicon Nanoantennas
Dorian Bouchet, Mathieu Mivelle, Julien Proust +9
Substituting noble metals for high-index dielectrics has recently been proposed as an alternative strategy in nanophotonics to design broadband optical resonators and circumvent th…
Diamond photonics platform enabled by femtosecond laser writing
Belen Sotillo, Vibhav Bharadwaj, J. P. Hadden +14
We demonstrate the first buried optical waveguides in diamond using focused femtosecond laser pulses. The properties of nitrogen vacancy centers are preserved in the waveguides, ma…
Monolithic AlGaAs second-harmonic nanoantennas
V. F. Gili, L. Carletti, A. Locatelli +9
We demonstrate monolithic aluminum gallium arsenide (AlGaAs) optical anoantennas. Using a selective oxidation technique, we fabricate such epitaxial semiconductor nanoparticles on…
Mid-infrared surface plasmon polariton chemical sensing on fiber-coupled ITO coated glass
Javier Martinez, Airan Rodenas, Magdalena Aguilo +3
A novel fiber-coupled ITO coated glass slide sensor for performing surface plasmon polariton chemical monitoring in the 3.5 um mid-IR range is reported. Efficient mid-IR fiber coup…
phase control in circular multicore fibers
Stefano Longhi
We consider light dynamics in a circular multicore fiber with balanced gain and loss core distribution, and show that transition from unbroken to broken phases can b…
Optical parametric amplification and oscillation assisted by low-frequency stimulated emission
Stefano Longhi
Optical parametric amplification/oscillation provide a powerful tool for coherent light generation in spectral regions inaccessible to lasers. Parametric gain is based on a frequen…
Non equilibrium optical properties in semiconductors from first--principles: a combined theoretical and experimental study of bulk silicon
Davide Sangalli, Stefano Dal Conte, Cristian Manzoni +2
The calculation of the equilibrium optical properties of bulk silicon by using the Bethe--Salpeter equation solved in the Kohn--Sham basis represents a cornerstone in the developme…
