Large Beam Size Grating Coupler in Silicon‐on‐Insulator Using Fully Etched Subwavelength Gratings

Laser &Photonics Reviews, EarlyView.
A fully etched, double‐period subwavelength structure is used to design a silicon‐on‐insulator grating coupler for large, well‐collimated off‐chip beams. The work experimentally demonstrates the generation of a 350‐micron wide beam, with a 54% radiation efficiency, thereby enabling efficient interaction with targets centimeters away from the chip ...

Discrete Chiral Ballistic Polariton Laser

Laser &Photonics Reviews, EarlyView.
Planar microcavities in the strong light–matter coupling regime exhibit exciton‐polariton modes with a strong chiral response toward circularly polarized light. This feature is exploited alongside inherent spin‐orbit coupling of cavity light to generate giant discrete optical vortices in polygonal arrays of exciton‐polariton condensates.

Photonic‐Defect Cavities as Next‐Generation Room‐Temperature Microlasers: A Comparative Study with Micropillars

Laser &Photonics Reviews, EarlyView.
A hybrid semiconductor–dielectric microcavity is demonstrated with embedded InGaAs quantum dots, enabling stable continuous‐wave lasing at room‐temperature. Outperforming thermally limited micropillars, the quasi‐planar design supports elevated‐temperature operation, validated through advanced quantum optical characterization, and offers a scalable ...

Surfactant‐Modified Progesterone‐Loaded PVP/Cellulose Fibres for Future Drug Delivery Applications in Menopause

Macromolecular Materials and Engineering, EarlyView.
Surfactant‐modified progesterone‐loaded PVP/cellulose fibres present a novel transdermal drug delivery system for hormone replacement therapy in menopause. Electrospun ethyl cellulose and cellulose acetate matrices, optimised by inclusion of polysorbate 80, are studied via SEM, FTIR, rheology, and in vitro studies and found to have improved structure ...
