Origin of the Laser‐Induced Picosecond Spin Current Across Magnetization Compensation in Ferrimagnetic GdCo

Advanced Optical Materials, EarlyView.
Picosecond spin current pulses generated by ferrimagnetic GdCo are studied via THz emission spectroscopy. Due to the GdCo micromagnetic structure, the spin current vanishes at compensation when a magnetic field is applied but persists for zero field. At room temperature, the THz spin current is dominated by Co. At low temperatures, Gd can significantly

Femtosecond Pulse Shaping with Semiconductor Huygens' Metasurfaces

Advanced Optical Materials, EarlyView.
Spatially variant silicon Huygens' metasurfaces enable femtosecond pulse shaping by tailoring the spectral phase and amplitude of incident pulses. Two key functionalities are demonstrated: temporal stretching and pulse splitting of an input Gaussian pulse.

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 ...

Rapid Electro‐Thermal Micro‐Actuation of Flat Optics Enabled by Laser‐Induced Graphene on Colorless Polyimide Substrates

Advanced Optical Materials, EarlyView.
Laser‐induced graphene (LIG) on a colorless polyimide (CPI) substrate functions as both an electrical heater and a heat spreader, enabling rapid electro‐thermo‐optic actuation. The system achieves reflective beam scanning up to 2 kHz and diffractive beam steering with 0.5‐millidegree resolution and a 0.9 s response time, showcasing LIG‐CPI as a soft ...
