Geometry‐Driven Whispering‐Gallery Modes in Self‐Assembled Phosphorescent Organic Microtubes
Advanced Optical Materials, EarlyView.Micelles encapsulating tris(2‐phenylpyridine)iridium(III) self‐assemble into a hollow hexagonal microtube stabilized by a surface passivation layer. The hexagonal cross‐section confines circulating light along its facets, sustaining sharp whispering‐gallery resonances that guide photoluminescence emission under laser excitation.

SU-8 Based Waveguide for Optrodes
Proceedings, 2018 Neural probes can be equipped with light for optogenetics applications. Different approaches are used for delivering light to the tissue: an optical fiber coupled to the probe, a µLED or a waveguide integrated on the probe.

Photoluminescent Color Centers on a Mainstream Silicon Photonic Foundry Platform
Advanced Optical Materials, EarlyView.Silicon photonic chips route and process light efficiently but are inherently inefficient at generating it. Here, bright light‐emitting defects, W‐centers, are written into the silicon layer of finished chips from a mainstream commercial foundry: high‐energy ions are implanted straight through the protective oxide and activated by a 250∘C$^\circ{\rm C}$

Massively Degenerate Coherent Perfect Absorption in Gradient‐Index Fibers
Advanced Optical Materials, EarlyView.A coherent perfect absorber (CPA) normally operates for only one or very few spatial modes. The CPA proposed here uses a gradient‐index (GRIN) fiber to absorb hundreds of spatial modes at once, its self‐imaging property replacing the bulky free‐space degenerate cavity of earlier designs. An analytic criterion sets how much modal degeneracy is required,
