TL;DR: By preventing the appearance of the nematic phase during the curing process, it is possible to avoid the formation of liquid-crystal droplets and obtain a sharp and uniform morphology, which reduces scattering losses and increases diffraction efficiency.

TL;DR: An innovative array of organic, color-tunable microlasers which are intrinsically phase locked are presented, embedded within periodic, polymeric microchannels sculptured by light through a single-step process.

TL;DR: In this paper, the photoinduced formation of switchable diffraction gratings in polymer-based liquid-crystalline composite materials is modeled as a mass diffusion process and a realistic kinetic description of polymerization processes.

TL;DR: In this article, a simple method is presented to control and trigger the coupling between plasmonic particles using both a growing process of gold nanoparticles (GNPs) and a mechanical strain applied to the elastomeric template where these GNPs are anchored.

TL;DR: A chemical-diffusive model that, taking into account sample temperature and intensity of the curing radiation, indicates the best conditions to fabricate holographic gratings, and a Kogelnik-like model that accounts for the dependence of the diffraction efficiency on material parameters, sample temperature, and applied electric field are reviewed.
