Initial tamper tests of novel tamper-indicating optical physical unclonable functions.
TLDR
Tamper-indicating O-PUF seals are developed using polyurethane adhesives with dispersed nanoparticles, where authentication is performed by use of wavefront-shaping controlled reflection, the first demonstration of the validity of this technique for use as tamper-Indicating seals.

Photodegradation and self-healing in a Rhodamine 6G dye and $$\hbox {Y}_{2}\hbox {O}_{3}$$Y2O3 nanoparticle-doped polyurethane random laser
AbstractOne of the fundamental difficulties in implementing organic dyes in random lasers is irreversible photodegradation of the dye molecules, leading to loss of performance and the need to replace…

Low-threshold and narrow linewidth diffusive random lasing in rhodamine 6G dye-doped polyurethane with dispersed ZrO_2 nanoparticles
We report on low-threshold and narrow linewidth intensity feedback random lasing in rhodamine 6G dye-doped polyurethane with dispersed ZrO2 nanoparticles. Depending on the dye/particle concentration,…

Self-healing organic-dye-based random lasers.
TLDR
The observation of "reversible" photodegradation in a Rhodamine 6G and ZrO2 nanoparticle-doped polyurethane random laser finds that during degradation, the emission broadens, redshifts, and decreases in intensity.

Microgenetic optimization algorithm for optimal wavefront shaping.
TLDR
A microgenetic optimization algorithm (μGA) for optimal wavefront shaping is developed and it is found that both genetic algorithms are more resistant to noise and sample decoherence than the iterative algorithm.

Random lasing and reversible photodegradation in disperse orange 11 dye-doped PMMA with dispersed ZrO2 nanoparticles
We report the observation of intensity feedback random lasing at 645 nm in Disperse Orange 11 dye-doped PMMA (DO11/PMMA) with dispersed ZrO$_2$ nanoparticles (NPs). The lasing threshold is found to…

Two-color thermosensors based on [Y$$_{1-x}$$1-xDy$$_x$$x(acetylacetonate)$$_3$$3(1,10-phenanthroline)] molecular crystals
We develop a two-color thermometry (TCT) phosphor based on [Y$$_{1-x}$$1-xDy$$_x$$x(acetylacetonate)$$_3$$3(1,10-phenanthroline)] ([Y$$_{1-x}$$1-xDy$$_x$$x(acac)$$_3$$3(phen)]) molecular crystals for…

Classical model of the upper bounds of the cascading contribution to the second hyperpolarizability
We investigate whether microscopic cascading of second-order nonlinearities of two molecules in the side-by-side configuration can lead to a third-order molecular nonlinear-optical response that…
