Blue shift of spontaneous emission in hyperbolic metamaterial. [PDF]
Sci Rep, 2014 Spontaneous emission is one of the most fundamental quantum phenomena in optics. Following the seminal work of Purcell and in agreement with the Fermi's Golden Rule, its rate can be controlled with the photonic density of states (PDOS). In recent years, this effect has been demonstrated in metamaterials with hyperbolic dispersion--highly anisotropic ...

Observation of Ultrashort Laser Pulse Evolution in a Silicon Photonic Crystal Waveguide
Micromachines, 2021 Using the sum frequency generation cross-correlation frequency-resolved optical gating (SFG-XFROG) measurement setup, we observed the soliton evolution of low energy pulse in an Si photonic crystal waveguide, and it exhibited the pulse broadening, blue ...

Blue-light background impairs visual exogenous attention shift
Scientific Reports, 2023 Previous research into the effects of blue light on visual-spatial attention has yielded mixed results due to a lack of properly controlling critical factors like S-cone stimulation, ipRGCs stimulation, and color.

Response of Photonic Hydrogels of Homogeneous Particles to Uranyl Ions in Aqueous Solutions
Photonic Sensors, 2023 We study here the response of photonic hydrogels (PHs), made of photonic crystals of homogeneous silica particles in polyacrylamide hydrogels (SPHs), to the uranyl ions UO 2 2+ in aqueous solutions. It is found that the reflection spectra of the SPH show
