Nonlocal response in plasmonic waveguiding with extreme light confinement
We present a novel wave equation for linearized plasmonic response, obtained by combining the coupled real-space differential equations for the electric field and current density.

Giant Birefringence of Periodic Dielectric Waveguides
The giant (Δn >; 1.5) and broadband achromatic birefringence is realized by periodic dielectric waveguides (PDWs), which benefit from low loss transmission, compact size, and simple structure.

Pullulan, a biomass‐derived polysaccharide, is transformed into transparent optical fibers using a solvent‐free borax hydrogel‐spinning method. The fibers outperform PMMA with ≈200 MPa tensile strength and 200 °C stability, while uniquely guiding visible‐to‐NIR light and enabling additive‐free humidity sensing.

Compact Single-Mode Silicon Hybrid Rib/Strip Waveguide With Adiabatic Bends
We report a low-loss, hybrid silicon waveguide geometry that consists of straight rib sections with a propagation loss of 0.27 ± 0.012 dB/cm and compact photonic wire bends.

Tailorable stimulated Brillouin scattering in nanoscale silicon waveguides [PDF]
Nanoscale modal confinement is known to radically enhance the effect of intrinsic Kerr and Raman nonlinearities within nanophotonic silicon waveguides. By contrast, stimulated Brillouin-scattering nonlinearities, which involve coherent coupling between ...

Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.
