TL;DR: In this article, a novel approach for making reconfigurable optical components that are created with light in a non-volatile and reversible fashion is reported, where components are written, erased and rewritten as two-dimensional binary or greyscale patterns into a nanoscale film of phase-change material by inducing a refractive index-changing phase transition with tailored trains of femtosecond pulses.

TL;DR: A switchable perfect absorber with multispectral thermal imaging capability and utilizing the amorphous-to-crystalline phase transition in GST offers switchable absorption with strong reflectance contrast at resonance and large phase-change-induced spectral shifts.

TL;DR: Non-volatile, bidirectional, all-optical switching in a phase-change metamaterial delivers high-contrast transmission and reflection modulation at near- to mid-infrared wavelengths in device structures down to ≈1/27 of a wavelength thick.

TL;DR: Differential scanning calorimetry (DSC) is widely used to study the stability of amorphous solids, characterizing the kinetics of crystallization close to the glass-transition temperature Tg as discussed by the authors.

TL;DR: In this paper, the frequency shift of a narrowband Fano resonance mode in a plasmonic planar metamaterial induced by a change in the dielectric properties of an adjacent chalcogenide glass layer was demonstrated.
