Simulation‐Driven Optimization of a Borosilicate/Al/Al2O3/Graphene Multilayer SPR Sensor for Aqueous Detection of Metal Ions and Their Binary Mixtures

Electron, EarlyView.
A cost‐effective surface plasmon resonance sensor using a borosilicate prism, 60 nm aluminum, an optimized 8–10 nm Al2O3 spacer, and graphene oxide achieves up to 338(°)/RIU sensitivity with narrow linewidth, enabling reliable detection and discrimination of Hg(II), Pb(II), Zn(II), and their binary mixtures in water.

3D Printing a Clinically Available Solution From Plaster‐Based Positives in Superficial Radiation Therapy

Journal of Medical Radiation Sciences, EarlyView.
This study compares two techniques for creating lead shielding masks to replace the current process for superficial/orthovoltage facial radiotherapy: Plaster Cast Positive Mould (PCPM), CT Scanned 3D Print (CT3DP), and Optical Scan 3D Print (OS3DP). CT3DP was found to be more accurate and preferred over OS3DP.

Diffraction‐Free Natural Optical Skyrmions and Their Subwavelength Confinement Around Vortices

Laser &Photonics Reviews, EarlyView.
ABSTRACT Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has been based on wave engineering and has led so far to idealized waves that, in real settings, eventually diffract.

Optical Stimulation and Monitoring of the Peripheral Nervous System: Perspectives and Challenges Toward Clinical Translation

Laser &Photonics Reviews, EarlyView.
Optical neuromodulation with IR light allows stimulation of the PNS without the need for physical contact with the target nerve or without requiring any genetic modification. The clinical translation of this technique will pave the way to the development of neural interfaces for restoring sensory feedback in individuals with limb amputation.

Fabrication‐Tolerant GaAs/SiN Coupling Above the Loss Threshold for Quantum Photonic Applications

Laser &Photonics Reviews, EarlyView.
Reliable low‐loss optical coupling between GaAs and SiN waveguides for heterogeneous integration of single‐photon sources is demonstrated. By developing a fabrication‐aware numerical design approach and accounting for experimentally measured fabrication variations and scattering losses, coupling efficiencies meeting the < 10% loss requirement for ...
