Active analog tuning of the phase of light in the visible regime by bismuth-based metamaterials
Marina Garcia-Pardo, Eva Nieto Pinero, Amanda K. Petford-Long +2
Active and analog tuning of the phase of light is needed to boost the switching performance of photonic devices. However, demonstrations of this type of tuning in the pivotal visib…

Optical Properties of Bismuth Nanostructures Towards the Ultrathin Film Regime
Johann Toudert, Rosalia Serna, Claire Deeb +1
Bulk bismuth presents outstanding optical properties, such as a giant infrared refractive index (n near 10) and a negative ultraviolet visible permittivity induced by giant interba…

Mid-to-far infrared tunable perfect absorption by a sub - λ/100 nanofilm in a fractal phasor resonant cavity
Johann Toudert, Rosalia Serna, Marina García Pardo +3
Integrating an absorbing thin film into a resonant cavity is the most practical way to achieve perfect absorption of light at a selected wavelength in the mid-to-far infrared, as r…
