Dielectric Permittivity Tensor of Muscovite for Next Generation All Van Der Waals Broadband Photonic Components

Advanced Optical Materials, EarlyView.
Low‐index and low‐loss vdW muscovite represents an emerging robust dielectric platform for the creation of next‐generation all‐vdW nanophotonic architectures. Its utilization as a low‐index building‐block in all‐vdW multilayers enables extreme optical contrast when paired with MoS2, paving the way to the realization of few‐layer ultrathin DBS ...

Terahertz Phase Inversion via Field‐Free Spin‐Orbit Torque Switching in an Antenna‐Integrated Spintronic Heterostructure

Advanced Optical Materials, EarlyView.
This work demonstrates fast electrical control of the phase of broadband terahertz pulses using a field‐free spintronic emitter. An antenna‐integrated Ta/CoFeB/Pt heterostructure switches its magnetization through spin‐orbit torque with 1 μs$\umu{\rm s}$ electrical pulses, producing complete π$\pi$‐phase inversion without external magnetic fields ...
