Single crystals of monoaromatic compounds exhibiting both mechanical softness and optical properties have attracted significant scientific interest in recent years, but they are very scarce. Herein, single crystals of 1,3-diamino-2,4,5,6-tetrabromobe

The intrinsically lossy nature of plasmonic-based detection platforms necessitates the use of alternative nanophotonic platforms such as one-dimensional photonic crystals (1DPhCs) to exploit proper...

We investigate intensity fluctuations of a weakly scattering optofluidic random laser having coherent and incoherent emission fractions. The coherent part comprises random spikes, whereas the incoherent part forms a broad pedestal in the emission spe

This letter presents a non-destructive and simple method for simultaneous measurement of fiber-waveguide coupling loss and propagation loss of single-mode optical waveguides. The experiment includes the coupling of a medium bandwidth laser source to

We report the observation of replica symmetry breaking (RSB) in a weakly scattering optofluidic random laser (ORL). Coherent random lasing is indicated by the presence of narrow peaks rising out of the spectral background. This coherence helps to ide

The effect of the infiltration of volatile solvents in photonic crystals is experimentally studied. Silica particles were synthesized and the opal structures were fabricated by self-assembly technique. Solutions containing various concentrations of m

We report on the fabrication of sol-gel derived Eu-doped ZnO films and the effects of heat-treatment on their structural and optical properties. X-ray diffraction data analysis confirms the decrease in strain in the thin films with increasing heat-tr

Fabrication of ZnO-HfO2 hybrid nanocrystals embedded 70 SiO2-(30−x) HfO2-xZnO (x=0, 2, 5, 7 and 10 mol%) ternary glass-ceramic planar waveguides doped with 1 mol% Eu-ions, by sol-gel process and dip-coating technique has been reported. The effect o
