Sketch and Peel Focused Ion Beam Patterning of Black Phosphorus for Mid‐Infrared Photonics

open access: yesAdvanced Optical Materials, EarlyView.
“Sketch and peel” method nano‐fabricates black phosphorus (BP) with minimal damage. A focused‐neon ion beam “sketches” the pattern, followed by polyvinyl acetate‐based “peeling” to remove surrounding flakes. Thermal treatment preserves the mid‐infrared (MIR) emission of the isolated “Koala” structure, proving it as an enabling technology for future BP ...

Ellipticity‐Controlled Exceptional Points and Cross‐Polarized Phase Singularities in Multi‐Layer Silicon Guided Mode Resonant Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Omni‐polarizers that pull all input polarization states to an elliptical or linear polarization can be made using highly resonant bi‐layer metasurfaces. The ellipticity of the selected polarization can be controlled by choosing the layer separation.
