Title:“Photon management in electrospun polymer fibers: emission, scattering and amplification of light”

Polymer nanofibers are currently exploited in a variety of fields, such as tissue engineering, photonics, filtration, energy harvesting and nanoelectronics. As optical media, polymer nanofibers have intriguing and specific properties: they can embed metal nanoparticles, quantum dots and molecular light sources, they can transport light among distant optically-active nanostructures and they can be deposited in 2-dimensional and 3-dimensional architectures in a controlled fashion, forming complex networks of interacting photon sources.
Polymers fibers can be produced by electrospinning, which allows for tailoring and controlling the properties of individual nanofibers and of their networks. Demonstrated photonic devices and applications include UV light sources, sub-wavelength waveguides, optical amplifiers, nanofiber distributed feedback lasers, and electrospun fibers with coupled opto-mechanical properties. Here fundamentals of the electrospinning and printing methods will be presented and discussed.
Recent results on light-emitting polymer nanofibers, including light-confinement, waveguiding, multiple scattering, stimulated emission, random lasing and anisotropy of energy migration, will be presented as well. The research leading to these results has received funding from the European Research Council under the European Union’s Seventh Framework Programme (FP/2007-2013)/ERC Grant Agreement n. 306357 (ERC Starting Grant “NANO- JETS”, www.nanojets.eu).
