Polymer fiber mats provide white and full-color tunable lasing
Alina Szukalska, Kinga Halicka-Stepien, Jastin Poplawski +4
Random Lasing has become highly advantageous for achieving white laser emission. Utilizing multiple light scattering in disordered media allows for cost-effective and flexible desi…
Photothermal tuning of microparticle diffusion anisotropy in nematic lyotropic chromonic liquid crystal
Patrycja Kadzialka, Lech Sznitko, Pawel Karpinski
We report a photothermal approach to dynamically tuning the anisotropic diffusion of microparticles suspended in a lyotropic chromonic liquid crystal (LCLC) consisting of a 30 % aq…
Dye stabilization and wavelength tunability in lasing fibers based on DNA
Luana Persano, Adam Szukalski, Michele Gaio +8
Lasers based on biological materials are attracting an increasing interest in view of their use in integrated and transient photonics. DNA as optical biopolymer in combination with…
Stacked electrospun polymer nanofiber heterostructures with tailored stimulated emission
Lech Sznitko, Luigi Romano, Dominika Wawrzynczyk +3
We present stacked organic lasing heterostructures made by different species of light-emitting electrospun fibers, each able to provide optical gain in a specific spectral region.…
Interplay of Stimulated Emission and Fluorescence Resonance Energy Transfer in Electrospun Light-Emitting Fibers
Lech Sznitko, Luigi Romano, Andrea Camposeo +4
Concomitant amplified spontaneous emission (ASE) and Förster resonance energy transfer (FRET) are investigated in electrospun light-emitting fibers. Upon dye-doping with a proper F…
Physically transient photonics: random vs. distributed feedback lasing based on nanoimprinted DNA
Andrea Camposeo, Pompilio Del Carro, Luana Persano +5
The authors report on a room-temperature nanoimprinted, DNA-based distributed feedback (DFB) laser operating at 605 nm. The laser is made of a pure DNA host matrix doped with gain…
