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.

  3. Random Lasers

    0.0 out of 5 stars 

    Online Presentations | 19 May 2006 | Contributor(s):: Mikhail A. Noginov

    Random lasers are the simplest sources of stimulated emission without cavity, with the feedback provided by scattering in a gain medium. First proposed in the late 60’s, random lasers have grown to a large research field. This lecture reviews the state of the art of random lasers, provides...

  6. Plasmonic Nanophotonics: Coupling Light to Nanostructure via Plasmons

    4.5 out of 5 stars 

    Online Presentations | 03 Oct 2005 | Contributor(s):: Vladimir M. Shalaev

    The photon is the ultimate unit of information because it packages data in a signal of zero mass and has unmatched speed. The power of light is driving the photonicrevolution, and information technologies, which were formerly entirely electronic, are increasingly enlisting light to communicate...
