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…

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…

Enhanced sensitivity of sub-THz thermomechanical bolometers exploiting vibrational nonlinearity
L. Alborghetti, B. Bertoni, L. Vicarelli +10
A common approach to detecting weak signals or minute quantities involves leveraging the localized spectral features of resonant modes, whose sharper lines (i.e. high Q-factors) en…
