Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

open access: yesAdvanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

An Efficient Diamond Raman Amplification Scheme Based on Adaptive Temporal Synchronization

open access: yesAdvanced Photonics Research, EarlyView.
This work reveals an adaptive temporal synchronization effect in delayed diamond Raman amplification, where the Stokes pulse shifts toward the fundamental peak. A periodic amplification scheme based on this phenomenon enables efficient pump recycling and enhanced energy conversion, offering a robust, delay‐tolerant strategy for advanced nonlinear ...

Integration of Soft‐Robotics and Deep Learning to Assess the Coordinated Biosonar Emission and Reception Dynamics in Hipposiderid Bats

open access: yesAdvanced Robotics Research, EarlyView.
Combining a biomimetic soft‐robot with deep‐learning data analytics sheds light on a unique peripheral dynamics seen in the biosonar system of bats: Bats modulate their ultrasonic biosonar signals upon emission as well as reception with variable, yet highly coordinated motion patterns of their noseleaves and pinnae.
