[ANGLÈS] Design of a depolarization channel at the wavelength of 532 nm for the UPC EARLINET lidar

We address the interplay between two fundamentally different wave-packet localization mechanisms, namely, resonant dynamic localization due to collapse of quasienergy bands in periodic media and disorder-induced Anderson ...

Optical metasurfaces have shown to be a powerful approach to planar optical elements, enabling an unprecedented control over light phase and amplitude. At that stage, where a wide variety of static functionalities have ...

We present a proof of concept prototype of a time-domain diffuse optics probe exploiting a fast Silicon PhotoMultiplier (SiPM), featuring a timing resolution better than 80 ps, a fast tail with just 90 ps decay time-constant ...

We experimentally observe formation of narrow laser beams behind the woodpile photonic crystal, when the beam remains well collimated in free propagation behind the crystal. We show that the collimation depends on the input ...

A recently-developed experimental equipment for optical measurements with acoustical proposes of vibrating parts of musical instruments is described in this thesis. Its methodology consists of performing optical measurements ...

In this work we report the image quality analysis of an antique microscope objective from ca 1850 by using a non-contact technique based on a Shack-Hartmann wavefront sensor. The method and the experiment are described, ...

The optical data transport system of the KM3NeT neutrino telescope at the bottom of the Mediterranean Sea will provide more than 6000 optical modules in the detector arrays with a point-to-point optical connection to the ...

This article proposes, analyzes, and tests a wake-up circuit for a microcontroller (MCU) that uses a light-emitting diode (LED), operating as a photodetector, illuminated by a smartphone flashlight. The wake-up circuit ...
