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…
Bridging mid and near infrared by combining optomechanics and self mixing
Tecla Gabbrielli, Chenghong Zhang, Francesco Cappelli +8
This work describes a self-mixing-assisted optomechanical platform for transferring information between near- and mid-infrared radiation. In particular, the self-mixing signal of a…
Gigahertz modulation of a fully dielectric nonlocal metasurface
Alessandro Pitanti, Gaia Da Prato, Giorgio Biasiol +2
Nonlocal metasurfaces are currently emerging as advanced tools for the manipulation of electromagnetic radiation, going beyond the widely explored Huygens metasurface concept. None…
Room-temperature silicon platform for GHz-frequency nano-electro-opto-mechanical systems
