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.

Large-scale first principles configuration interaction calculations of optical absorption in boron clusters
07 Mar 2012 | | Contributor(s):: Ravindra L Shinde
We have performed systematic large-scale all-electron correlated calculations on boron clustersBn (n=2–5), to study their linear optical absorption spectra. Several possible isomers of each clus-ter were considered, and their geometries were optimized at the coupled-cluster singles doubles(CCSD)...
ECE 616 Student Presentation: Ultrafast Non-linear Plasmonics
02 Mar 2012 | | Contributor(s):: Gururaj V Naik
Plasmonics has gained significant attention in the recent days owing to its capability of providing sub-wavelength confinement of light. As a consequence of sub-wavelength confinement of electric field, the field intensity issignificantly enhanced. High field intensity achieved by plasmonics,...
