Large Bidirectional Refractive Index Change in Silicon‐rich Nitride via Visible Light Trimming

Advanced Optical Materials, EarlyView.
Continuous‐wave visible light trimming of PECVD silicon‐rich nitride micro‐ring resonators enables precise, large bidirectional refractive index tuning. Resonance shifts as fine as 10 pm are achieved with a cost‐effective setup, demonstrating large red shifts of 49.1 nm and blue shifts of 10.6 nm.

Colossal Terahertz Emission with Ultrafast Tunability Based on Van der Waals Ferroelectric NbOI2

Advanced Optical Materials, EarlyView.
The widespread THz applications are hindered by the scarcity of efficient ultrafast THz sources with on‐demand fast modulation and easy on‐chip integration capability. Here the discovery of colossal THz emission is reported from a van der Waals (vdW) ferroelectric semiconductor NbOI2 and demonstrates the ultrafast coherent control of the THz emission ...

Few Photons Probe Third‐Order Nonlinear Properties of Nanomaterials in a Plasmonic Nanocavity

Advanced Optical Materials, EarlyView.
It is demonstrated that a few photons probe the nonlinear optical properties of different nanomaterials inside a plasmonic nanocavity. A simple analytical model fits the experimental result, which shows a strong dependence on the nanocavity resonance.

Suppressed Stokes Shifts and Hot Luminescence from Quantum Dots within Plasmonic Nanocavities

Advanced Optical Materials, EarlyView.
This study demonstrates the suppression of the Stokes shift in lead sulfide quantum dots through integration with plasmonic nanocavities. By enhancing spontaneous emission and altering exciton relaxation pathways, this approach enables direct band‐edge emission with improved radiative efficiency, highlighting the powerful role of nanophotonic ...
