Antimony sulfide, or stibnite (Sb 2 S 3), has been investigated intensively in recent years as a promising material for nontoxic, environmentally friendly solar cells. It is now possible to fabricate ...
For a mode conversion process, the propagation constant of the guided wave changes from the input mode β in to the output mode β out, which can be expressed as β in − β out = k 0 (n in − n in) = N ⋅ ...
In the paper, we provide an extremely narrow EIT transmission band by coupling optical waveguide mode to the broad low-transmission spectrum of plasmonic nanowire pairs in a free-standing bilayer ...
Lithium niobite (LN) with an ultra-wide optical transparent window has shown excellent nonlinear, electro-optic, acoustic-optic, piezoelectric, thermoelectric and photorefractive effects. It is an ...
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 ...
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 ...
(Nanowerk Spotlight) The concepts of metamaterials and metasurfaces have spawned massive novel applications in free-space optics. However, recent research also indicates that they possess prominent ...
What are modal effects? Integrated photonics—the devices and the materials used to make them happen. One of the key planar-waveguide configurations: the ring resonator. The roots of waveguide optics ...
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 ...
