Arduino based interferometer stabilizer equipped with a digital lock-in amplifier
Giuseppe Emanuele Lio, Saravanan Rajamani, Alessandro Pitanti +2
Interferometric sensors are ubiquitous in precision metrology, yet their performance is fundamentally limited by environmental noise and thermal drift. To achieve maximum sensitivi…
Coherent absorption reveals colors hidden in a grey Fabry-Pérot cavity
Giuseppe E. Lio, Giulio Carotta, Lorenzo Lavista +8
Thin dielectric films are known to show distinct colors, responsible for the iridescence of various natural and artificial objects such as insect wings and soap bubbles. In the pre…
Near-visible low power tuning of nematic-liquid crystal integrated silicon nitride ring resonator
Jayita Dutta, Antonio Ferraro, Arnab Manna +5
The development of compact, low-power, and high-performance integrated photonic phase shifters is critical for advancing emerging technologies such as light detection and ranging (…
Unlocking optical coupling tunability in epsilon-near-zero metamaterials through liquid crystal nanocavities
Giuseppe Emanuele Lio, Antonio Ferraro, Bruno Zappone +6
Epsilon-near-zero (ENZ) metamaterials represent a powerful toolkit for selectively transmitting and localizing light through cavity resonances, enabling the study of mesoscopic phe…
Tailoring of Plasmonic Functionalized Metastructures to Enhance Local Heating Release
Antonio Ferraro, Giuseppe Emanuele Lio, Abdelhamid Hmina +3
Plasmonic nanoheaters are reported that produce a significant local heating when excited by a 532 nm wavelength focussed laser beam. A significant temperature increase derives from…
Color Tuning by Spontaneous Propagation of Gap Surface Plasmons in Epsilon Near Zero Nano-Cavity
Giuseppe Emanuele Lio, Antonio Ferraro, Michele Giocondo +2
This work presents numerical and experimental results of plasmonic Metal-Insulator optical nano-cavities. The systems are composed of Silver as metal, polyvinylpyrrolidone or indiu…
