Laser Direct Writing via Two Photon Polymerization (LDW via TPP), also known as 3D Lithography (3DL), is a method of obtaining structures with sub-micrometric features (lateral features down to 90 nm) using LDW. The key element is the two-photon absorption and the transverse Gaussian intensity profile of the incident laser beam. Irradiation of the used…
EUREKA! TT s.r.l., the investment company of “Eureka! Fund I – Technology Transfer” (https://www.eurekaventure.it/) that finances Proof-of-Concept (POC) projects of Italian universities and research centers, has chosen to fund through an innovation contract the CNR – Institute of Applied Sciences and Intelligent Systems “Eduardo Caianiello” (ISASI) together with the ENEA – Italian National Agency for…
The 12th and 13th of September 2022, the PULSE-COM project organised the 2nd edition of the Summer School on Smart Materials for Opto-Electronic Applications in hybrid format. Thanks to the talented and experienced speakers who intervene this edition had been a real success. The aim of that school was to bring to the attendees the…
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…
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…
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…
For experiments of bending process of PMP samples used different radiation sources as (a) High Power LED, (b) Laser Diode Red integrated module, (c) Halogen light source. 1. The high power LED (Figure 1) with the parameters of the labels as below Nominal Wavelength 385 nm LED Output Power(Min/Typ.) 1240 nW / 1780 mW Bandwidth(FWHM)…
