Laser &Photonics Reviews, EarlyView.Fully exploiting the broad untapped terahertz spectrum necessitates extending the bandwidth of practical guided‐wave systems. This work introduces a substrateless quasi‐optical integration platform to meet this need. Classical optical principles going back to the time of Michelson are adapted to a planar, micro‐machined, monolithic‐silicon platform ...

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.

1 PHz of Coherent Bandwidth from a Compact Fiber Device
Laser &Photonics Reviews, EarlyView.A coherent comb spectrum with an unprecedented bandwidth of 1 PHz, spanning from the deep ultraviolet (280 nm) to the mid‐infrared (2700 nm), is generated by a compact fiber device. The integrated, novel pulse purification technology enables broadband dispersion control and the synthesis of low‐noise, single‐cycle near‐infrared pulses with a clean ...

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 ...

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 ...
