Back Cover: Deep‐subwavelength light confinement and transport in hybrid dielectric‐loaded metal wedges (Laser Photonics Rev. 8(4)/2014)

Hybrid dielectric‐loaded metal wedges for deep‐subwavelength light confinement and transport. The goal of confining light at a deep‐subwavelength scale while retaining moderate attenuation remains one of the major challenges in nanophotonics. By using hybrid metal wedges covered with lowhigh‐index dielectric claddings, the authors demonstrate strategies for high performance light transport at the sub‐diffraction‐limited level. Nanoscale mode size, reasonable propagation distance in conjunction with low waveguide crosstalk can be achieved simultaneously.
