Nonlinear Optical Microscopy of Semiconductor–Metal Nanocavities

Advanced Photonics Research, EarlyView.
Three‐dimensional nonlinear optical microscopy is used to visualize GaAs–gold hybrid nanocavities. By carefully selecting the pump wavelength to position the harmonic generation at the nanopillar resonance, an enhanced contrast is observed in the nonlinear imaging.

Design and Characterization of Low‐Threshold InP Nanowire Photonic Crystal Surface‐Emitting Lasers

Advanced Photonics Research, EarlyView.
The lasing performance of nanowire (NW) photonic crystal surface‐emitting lasers (PCSELs) is highly sensitive to changes in the photonic crystal lattice constant and the NW diameter. This study systematically investigates the threshold power and the threshold gain for different PCSEL geometries.

Local Structure–Luminescence Correlation in Eu3+‐Doped Phosphors: A Comprehensive Review

Advanced Photonics Research, EarlyView.
This review discusses the correlation between local structure and the luminescent properties of Eu3+ ions, and also summarizes analytical methods for determining Eu3+ site occupancy. The luminescence properties of the phosphors are determined by the electronic configuration of the activator ions and are also affected by the coordinated environment of ...

Recent Progress in Strategies to Enhance the Spin‐Orbit Coupling of Multiresonance Thermally Activated Delayed Fluorescent Materials for Narrowband Organic Light‐Emitting Diodes

Advanced Photonics Research, EarlyView.
For multiresonance thermally activated delayed fluorescent emitters, the reverse intersystem crossing (RISC) process is of paramount importance. This review summarizes two approaches to enhance the RISC rate by improving spin‐orbit coupling: the heavy atom strategy and the long‐range charge‐transfer/short‐range charge‐transfer strategy.

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

Advanced 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.
