Hopfield-like open channel retrieval for disordered optical media
Marco Leonetti, Luca Leuzzi, Giancarlo Ruocco
The measurement of the optical Transmission Matrix (TM) enables to access "open channels": input patterns, specific to each scattering structure, capable to deliver very high trans…
Spatial coherence of light inside three dimensional media
Marco Leonetti, Lorenzo Pattelli, Simone De Panfilis +2
Speckle is maybe the most fundamental interference effect of light in disordered media, giving rise to fascinating physical phenomena and enabling applications in imaging, spectros…
Scattering Assisted Imaging
Marco Leonetti, Alfonso Grimaldi, Silvia Ghirga +2
An ideal imaging system provides a spatial resolution that is ultimately dictated by the numerical aperture (NA) of the illumination and collection optics. In biological tissue, re…
Hyperuniformity in amorphous speckle patterns
Diego Di Battista, Daniele Ancora, Giannis Zacharakis +2
Hyperuniform structures possess the ability to confine and drive light, although their fabrication is extremely challenging. Here we demonstrate that speckle patters obtained by a…
Momentum selection for enhanced adaptive focusing through semi-transparent media
Diego Di Battista, Giannis Zacharakis, Marco Leonetti
Adaptive optics can focus light through opaque media by compensating the random phase delay acquired while crossing a scattering curtain. The technique is commonly exploited in man…
Active subnanometer spectral control of a random laser
Marco Leonetti, Cefe Lopez
We demonstrate an experimental technique that allows to achieve a robust control on the emission spectrum of a micro random laser and to select individual modes with sub-nanometer…
