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 ...

Toward Enhancing Chiro‐Optical and Magneto‐Optical Properties of Magnetic Nanocrystals by Surface Plasmons

open access: yesAdvanced Optical Materials, EarlyView.
Here, recent progress is highlighted in colloidal magnetoplasmonic hybrid nanomaterials, with a focus on chiral plasmonics. Metal nanocrystals with intrinsic chiroptical features can lead to a combination of chiral plasmonics and magneto‐optics effects when interacting with the magnetic counterpart, offering a foundation for systematically designing ...

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.

High‐Endurance and Energy‐Efficient All‐Optical Programming of Scalable Silicon Waveguides with Integrated Phase‐Change Material Patches

open access: yesAdvanced Optical Materials, EarlyView.
Phase change materials are integrated into silicon photonic circuits via 200 mm industrial wafer processes. Interferometric optical characterization reveals switching thresholds, transmission modulation, phase shifts, and record endurance (>108 cycles).
