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.

New horizons for nanophotonics [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017
The current progress in nanophotonics is explained by the excitement of achieving enhanced near-field effects and breaking the diffraction limit for light localization and imaging. Recent years have witnessed a growing research interest in the study of plasmonic structures made of the noble ...

Basis‐Independent Geometric Phase Modulation in Circularly Birefringent Plasmonic Structures

Advanced Optical Materials, EarlyView.
Here we introduce a plasmonic metasurface composed of spatially rotated chiral spiral unit cells designed to produce space‐variant circular retardance. This generates a geometric phase ramp equivalent to a blazed grating, leading to polarization dependent diffraction orders in momentum space.

Hyperuniform Disorder in Photonic Crystal Slabs With Intrinsic Non‐Hermiticity

Advanced Optical Materials, EarlyView.
Light propagation in photonic crystal slabs with imposed hyperuniform disorder is investigated theoretically and numerically. The hyperuniform disorder is imposed by varying the hole size. The photonic crystal is intrinsically non‐Hermitian due to radiative loss, with non‐Hermiticity appearing as a complex effective mass of a quadratic photonic band ...

Strong Enhancement of Er3+ Emission at Room Temperature in Si3N4 Metasurfaces

Advanced Optical Materials, EarlyView.
Erbium‐doped SiN metasurfaces are engineered to support Mie resonances at 1.55μm$1.55\text{}\mathrm{\mu}\mathrm{m}$, enhancing the local density of optical states and accelerating spontaneous emission. By optimizing nanocylinder radius and implantation depth, room‐temperature PL is increased about 18‐fold, while lifetime shortens by nearly an order of ...
