Description

When optical components are reduced to the nanoscale, they exhibit interesting properties that can be harnessed to create new devices. For example, imagine a block of material with thin layers of alternating materials. This creates a periodic arrangement of alternating dielectric constants, forming a "photonic crystal" that is analogous to the electronic crystals used in semiconductor devices. Photonic crystals, along with quantum dots and other devices patterned at the nanoscale, may form the basis for sensors and switches used in computers and telecommunications. More information on Nanophotonics can be found here.

  5. Three-Dimensional Photonic Crystals

    11 Feb 2008 | | Contributor(s):: Minghao Qi

    A photonic crystal (PhCs) is typically a composite of a high-dielectric-constant material (e.g. Si) and a low-constant one (e.g. SiO2 or air), arranged periodically in space. Two dimensional examples include a hexagonal lattice of air holes drilled in a Si slab, or a set of Si rods at square...

    06 Jun 2019 | | Contributor(s):: Joel Moore

    We then turn to how topological Weyl and Dirac semimetals can show unique electromagnetic responses; we argue that in linear response the main observable effect solves an old problem via the orbital moment of Bloch electrons, and how in nonlinear optics there should be a new quantized effect,...
