Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity

Advanced Optical Materials, EarlyView.
A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

Inverse Optical Contrast in Metastable GeTe2: An Anomaly Enabling Low‐Loss Phase Change Photonics

Advanced Optical Materials, EarlyView.
An anomalous optical phase inversion in GeTe2$\mathrm{GeTe_{2}}$ provides a new platform for low‐loss non‐volatile integrated photonics at 1550 nm. The transition from the amorphous state (1) to a metastable vdW−GeTe2$\mathrm{vdW-GeTe_{2}}$ crystalline phase (2) is driven by bandgap widening, resulting in a negative refractive index change (Δn$\Delta ...

Study on the Electrodeposition of Lead with In-Situ Ellipsometry

International Journal of Electrochemical Science, 2015
In this study, we applied the in situ spectroscopic ellipsometry (SE) technology to the electrochemical test, and combined with cyclic voltammetry (CV) mainly researched underpotential-deposited (UPD) of Pb on polycrystalline Cu.

Purely Equatorial Lasing in Spherical Liquid Crystal Polymer Microlasers with Bipolar Refractive Index Profile

Advanced Optical Materials, EarlyView.
Spherical liquid crystal polymer microlasers with a bipolar configuration confine lasing to a single equatorial plane, allowing precise control over where the laser emission is generated. The anisotropic refractive index profile additionally lifts the energy degeneracy of azimuthal whispering gallery modes, which causes a characteristic splitting into ...
