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.

Photonic Metamaterials: From Linear to Nonlinear Optics
14 Dec 2010 | | Contributor(s):: Natalia Litchinitser
Metamaterials open unparalleled opportunities for "engineering" previously inaccessible values of refractive indices from positive to near-zero and even negative values, and new avenues for light manipulation. While an enormous progress has been made in the field of linear optics of uniform...
Anti-Reflection Coating Assignment
30 Nov 2010 | | Contributor(s):: Alex Small
This is a guided activity for students to study the design of an anti-reflection coating. The student is first asked to do a simple calculation by hand, to determine the proper thickness for an anti-reflection coating in a standard situation. The student then uses the nanoHUB tool "PhotonicsRT:...

20 Sep 2010 | | Contributor(s):: Gabriel Popescu
Often, experiments involve light beams. A light beam can be defined as a distribution of field that fulfills the approximation in Eq. 20,i.e. is characterized by a dominant wave vector component, k(z) >> k(x) , k(y) . A beam is, therefore, the spatial equivalent of quasimonochromaticlight, where...
