In recent NRL-led work, the thickness of hBN surrounding a light-emitting TMD layer was carefully tuned in order to support optical waveguide modes. Researchers at NRL carefully assembled stacks of 2D ...
Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in ...
The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...
Fig. 1 Design and modal evolution of the SSC-integrated EDWA chip. (a) the schematic of the SSC-integrated EDWA chip, (b) the simulated modal evolution in the SSC region with the insets (i-v) showing ...
Scientists announce the discovery of slab waveguides based on the two-dimensional material hexagonal boron nitride. The U.S. Naval Research Laboratory (NRL), in collaboration with Kansas State ...
Two-dimensional (2D) materials are a class of materials which can be reduced to the monolayer limit by mechanically peeling the layers apart. The weak interlayer attractions, or van der Waals ...
