Nanophotonics, Volume 15, Issue 13, 13 July 2026.A novel ultra‐low loss, weakly coupled few‐mode hollow‐core anti‐resonant fiber is realized through truncated tubes and differential wall thickness, which can support eight spatial modes as independent channels. The effective refractive index difference between adjacent modes is greater than 1.0 × 10−4, and the intrinsic loss of all target modes at ...

Photonic Doping of Epsilon‐Near‐Zero Bragg Microcavities
Nanophotonics, Volume 15, Issue 13, 13 July 2026.Photonic doping of an epsilon‐near‐zero (ENZ) Bragg microcavity at optical frequencies induces strong magnetic responses from dielectric inclusions, enabling intense field localization, Purcell enhancement, and tunable hybrid Bragg–Mie modes. The platform supports perfect magnetic conductor and epsilon‐and‐mu‐near‐zero regimes, offering opportunities ...

This thesis is directed to laser cladding with powder and a CO2 laser as heat source. The laser beam intensity profile turned out to be an important pa6 Summary rameter in laser cladding. A numerical model was developed that allows the prediction of the surface temperature distribution that is attained with an arbitrarily shaped intensity profile ...
