Abstract Novel poly(dimethylsiloxane) (PDMS) doped with two different spiropyran derivatives (SP) were investigated as potential candidates for the preparation of elastomeric waveguides with UV-dependent optical properties. First, free-standing films

Malaria pigments were synthesized and characterized via FTIR and SEM analysis. We further demonstrate the magneto-optical malaria diagnosis using submicron-sized photonic crystal fiber. Our results constitute another step towards quick and cost-effec

Multimode laser emission generally takes place in homogeneously broadened gain media placed inside a standing-wave resonator due to spatial hole burning. Solutions proposed to eliminate this phenomenon have so far involved the use of intracavity elem

We present the design and experimental characterization of nanostructured laser mirrors aimed at suppressing spatial hole burning (SHB) of a standing wave resonator. The dielectric Bragg mirrors were made by GLancing Angle Physical Vapor Deposition.

The concept of the twisted-mode laser operation, which suppresses spatial hole burning and produces single-mode operation in a standing-wave resonator, is revisited for the case of optically anisotropic laser mirrors presenting arbitrary birefringent

Birefringent TiO2 thin films were characterized using spectroscopic ellipsometry. Ellipsometric data were fitted to a model, taking into account the anisotropic nature of the film and the coherence length of the source being shorter than the thicknes
