Optical polarization perturbed by shear strains of ultrasonic bulk waves in anisotropic semiconductors: Multiphysics modeling and optoacoustic validation

open access: yesPhotoacoustics, 2023
Characterization of lattice properties of monocrystalline semiconductors (MS) has been rapidly advanced. Of particular interest is the use of shear strains induced by optoacoustic-bulk-waves. However, this technique has been hindered owing to the lack of

Real‐Time Observation of Soliton Buildup and Self‐Organization in a GHz Harmonic Mode Locked Fiber Laser

open access: yesLaser &Photonics Reviews, EarlyView.
This image is an experimental recording of the buildup of harmonic mode‐locking in a fiber laser. The horizontal dimension corresponds to one cavity round trip, where the laser field intensity is displayed in a color scale. The vertical dimension is the evolution time in logarithmic scale, spanning from microseconds to seconds.

Automatic insect identification, counting, and monitoring techniques: a review

open access: yesPest Management Science, EarlyView.
Automated insect monitoring increasingly integrates optical, acoustic, infrared, radar, electrostatic, and biosensing technologies with artificial intelligence. No single approach is universally optimal; reliable deployment depends on task‐specific validation, representative datasets, robustness under field conditions, energy autonomy, connectivity ...
