Polarization‐Independent Complex Bragg Grating Filters on Silicon Nitride
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.

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 ...

How zero price affects demand?: experimental evidence from the Moroccan telecommunication market [PDF]
To select one of several products (or to buy nothing) is a daily decision. Its foundations vary from one person to another and are based on perceptions, preferences, and other criteria.

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

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
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 ...

Impact of Parasitic Conductive Interfaces on the DC and RF Performance of GaN‐on‐GaN HEMTs
GaN‐on‐GaN HEMTs suffering from a parasitic conductive interface show a power added efficiency drop from an expected 50 % to 15 %. The interface forms on GaN wafers prior to epitaxy due to Si contamination to absorb RF power, introduce propagation loss and loading effects, reduce gain by 50 %, and fmax and Pout by 40 % compared to GaN‐on‐SiC HEMTs ...
