Polarization‐Independent Complex Bragg Grating Filters on Silicon Nitride

Laser &Photonics Reviews, EarlyView.
This work demonstrates multi‐band polarization‐insensitive optical filters on the 400‐nm thick silicon nitride platform, complying with the LAN‐WDM standard. The filters are based on cladding‐modulated Bragg gratings with judiciously designed grating dimensions.

Monolithic Silicon Photonic Transceiver for 160 km Multi‐Channel Quantum Entanglement Distribution in Fiber Network

Laser &Photonics Reviews, EarlyView.
The paper demonstrates a chip scale (4.5 x 4.5 mm2) silicon integrated system that is capable of distributing entangled photons over 160 km single mode fibers without dispersion compensations and external optical filters. The results highlight the potential for massive production and large‐scale deployed quantum integrated circuits for a future ...

Vortex Beam Lasing from III‐V Nanowires Epitaxially Grown on Silicon‐on‐Insulator

Laser &Photonics Reviews, EarlyView.
An epitaxially grown InGaAs nanowire photonic crystal laser on silicon‐on‐insulator is demonstrated to emit vortex beams carrying orbital angular momentum. Deforming the honeycomb lattice causes the band inversion effect and creates symmetry‐protected bound states in the continuum, enabling single‐mode lasing with a topological charge of −2 ...

High Performance Compatibilized Polyamide Composites Containing Graphene Nanoplatelets and Recycled Glass Fibers

Polymer Composites, EarlyView.
Polyamide/graphene nanoplatelet composites for functional applications ABSTRACT Polyamide‐based composites reinforced with graphene nanoplatelets (GNPs) have exceptional potential as high‐performance functional materials. Non‐covalent modification with a trimellitic anhydride (TMA) coating agent improved the compatibility of the GNPs with polyamide 6 ...

Nucleation and Propagation of Traveling Charge Domains in a Planar AlGaN/GaN Triode Structure

physica status solidi (a), EarlyView.
This work presents a novel model for the nucleation of charge domain instabilities in semiconductors exhibiting negative differential drift velocity, identifying diffusion as the key factor inhibiting domain formation. A planar Gunn triode structure is proposed which overcomes obstacles to the realization of GaN‐based Gunn effect devices with ...

High‐Purity Single‐Photon Emission in the Telecom O‐Band from Droplet‐Epitaxy InAs Quantum Dots Integrated into a GaAs/AlGaAs Planar Microcavity on Vicinal GaAs(111)A Platform

Advanced Quantum Technologies, EarlyView.
High‐purity single‐photon emission at telecom O‐band is demonstrated from droplet‐epitaxy InAs quantum dots embedded in a GaAs/AlGaAs microcavity. Strain engineering via an InAlAs buffer enables broadband telecom emission with high purity, short lifetimes, and enhanced extraction.

Conceptualizing Resilience, Sustainability and Smartness for Building Fire Risk Management

Sustainable Development, EarlyView.
ABSTRACT Resilience, sustainability, and smartness (ReSuSm) within the building construction sector impact, or are impacted by building fires in one way or another. Hence, consideration of ReSuSm for building fire risk management (BFRM) is imperative to enhance safety and mitigate adverse impacts.
