Chemical Substitution‐Driven Design of a High‐Performance Noncentrosymmetric Bismuth Molybdenum Selenite

open access: yesAdvanced Optical Materials, EarlyView.
The first bismuth molybdenum selenite material with a macroscopic noncentrosymmetric structure is designed using a chemical substitution‐oriented approach and successfully synthesized via a hydrothermal reaction. It exhibits exceptionally well‐balanced nonlinear optical properties, including a s efficiency that is 1.2 times that of KTiOPO4, a suitable ...

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

open access: yesAdvanced 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.
