A customized Ti-Nano resin is used to fabricate 3D photonic crystals with a complete bandgap in the visible spectrum through a nanoscale printing technique. The 3D printed and annealed titania photonic crystals show perfect reflectance within the wavelength range associated with this bandgap.

Silica encapsulation can quench nonradiative relaxation and yield afterglow emission in materials. Here, the authors transfer this strategy to molecular emitters by doping them into silica microparticles enhancing both emission intensity and lifetimes.

Controlled generation of OAM modes holds promise for applications in classical and quantum communication networks. Here the authors develop an optical vortex ladder in which an input beam transforms into vortices mediated by the Berry phase winding around topological singularities at the Dirac points.

Topological lattices with long-range interactions enable increased Chern numbers and wide bandgaps, achieving defect-robust multichannel processing.

Platforms that exhibit moiré patterns have the potential to tailor band structures and control electromagnetic and mechanical waves. This Perspective discusses the current state of the art, challenges and outlook within the realm of classical wave physics.

Organic solvents are used to produce high-value crystals such as pharmaceuticals, organic semiconductors, and optical devices, but our understanding of the fundamental processes of crystal growth from organic solutions is limited. Here, the authors use time-resolved in situ atomic force microscopy to show a nonclassical, dual growth mode of etioporphyrin I crystals from mesoscopic solute-rich clusters.

We had all been wondering “where is Costas?” and now we learned that we shall not see him again. We have lost a good friend and leader in the photonics community.

Nanofabricated strained photonic crystals in silicon platforms enable the formation of photonic Landau levels at telecommunication wavelengths, with broad potential applications for enhanced light–matter interactions on-chip.

Nonlinear optical resonators allow the coherent conversion of photons, yet fabrication tolerances limit their wavelength accuracy. Introducing periodic modulation in ring resonators is shown to allow robust and predictable selection of the converted photons.

Whether Anderson localization of light is possible in three dimensions has long been an open question. Numerical calculations have now shown that it can be done with a disordered arrangement of metal particles.
