Azo-PMP: fast and adapted reactivity for optical micro-switch application

Introduction Photomobile polymers composed of azobenzene molecules (PMP-Azo) possess specific properties for photomechanical conversion. The mechanical deformation of these devices is based on the photoisomerization principle: Under U.V. light exposition the azobenzene molecules switch to “cis” form and the sample curves, Exposed to a wavelength above 405 nm the molecules revert back to their initial…

Optical Fibers alignment

The Optical Fibers (OF`s) alignment is one of very important operation to perform the optimal parameters of light beam as generated by a light source as for our project PULSE-COM works. For its application, we have used Laser Diodes (LD`s) of different colours including instant red colour with the wavelength of 635 nm. For the…

CNR improved the properties of PMPs decreasing azobenzene concentration and doping the PMP with ZnO nanoparticles using a solventless approach.

The PMPs when doped lost their ability to rotate the polarized light (Figure 1) but improved their bending capabilities and mechanical properties (Figure 2). In fact the doped material could bend more as compared with control when irradiated with laser light (Figure 1 A). Furthermore, the ZnO nanoparticles could improve the material ability to store…

A new strategy to improve the measurements and analysis at the nanoscale using Piezoresponse Force Microscopy in PULSE-COM project

Piezoelectric and semiconducting zinc oxide (ZnO) nanowires (NWs) are excellent candidates for the fabrication of energy harvesters, mechanical sensors, piezotronic and piezophototronic devices [1].  Understanding the interplay between piezoelectricity and semiconductor physics is fundamental to enhancing the performance of these devices. In PULSE-COM, within a strong collaboration of ENEA and UGA partners [2], a new…

Reconfigurable Optical Networks

Reconfigurable Optical Networks will be developed based on reconfigurable optical devices implementation into networks with new tunable and switchable functionalities by means of optical control. Between several optics devices with more specific functionalities we are working to perform the photonic devices with the specific functions like wavelength selector, multiplexer/de-multiplexer as well as even the spectrometer.…
