Nanotechnology - the Development of Photonic Materials, Which Produce, Guide, Detect, and Process Light.

Developments in the field of optical fiber transmission systems require faster transmission rates. Since photons travel faster than electrons, light can be utilized to increase the speed of transmission. Conventional photonic devices, such as diode lasers and optical waveguides, require the usage of an entire wavelength of light. This confines the devices to be at least as large as the wavelength of visible light (400-700 nanometers). Optical devices that utilize sub-wavelength light must be developed in order to make anything in the nano-scale. The advantage of these devices is the ability to perform functions based on local electromagnetic interactions in a much smaller area than is currently possible, leading to smaller nanophotonic circuitry. The development of a nanophotonic switch would be an essential component of a nanophotonic integrated circuit. A nanophotonic switch is a switch that utilizes photons instead of electrons on the nano-scale.
