Based on harnessing the power of light, photonics is the information-processing counterpart of electronics, using photons instead of electrons to far more efficiently process or transmit information, whether that it is inside a microchip, a drug delivery device, or even a living cell. On the nanoscale, the goal is to develop technologies that simply are not possible with conventional microelectronics. Emerging as a multidisciplinary new frontier of science and technology, nanophotonics is capturing the imagination of scientists and engineers worldwide. The first authoritative look at the subject, Nanophotonics is a comprehensive examination of the foundations, theory, fabrication, materials, and applications of nanophotonics.
