Laminated Multilayer Optical Waveguides Enabled by Floating Film Transfer
Advanced Materials Interfaces, EarlyView.A scalable floating film transfer process enables the lamination of sub‐micron polymer films into high‐quality multilayer optical waveguides. The method preserves optical performance, allows precise control over layer stacking, and supports the integration of high‐index‐contrast polymer/air gratings for efficient mode coupling in advanced photonic ...

The plane wave diffraction on a flat area from randomly orientated rectangular apertures
Results in PhysicsThe diffraction of a scalar wave field incident on a flat irregular diffraction grating with arbitrarily oriented rectangular apertures is considered. It is shown that if the random grating is illuminated from the far zone (the diffraction problem in the

Advanced Materials Interfaces, EarlyView.Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to
