Hyperuniform Disorder in Photonic Crystal Slabs With Intrinsic Non‐Hermiticity
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
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 ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
