Fiber optics is the fastest and reliable means of transferring large amounts of data Optical fiber links are used for local area networks to world wide data communication. Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. Digital optical communications explores the practical applications of this union...

By placing changeable nanofabricated structures (wires, dots, etc.) on an atom mirror one can design guiding and trapping potentials for atoms. These potentials are similar to the electrostatic potentials which trap and guide electrons in semiconductor quantum devices like quantum wires and quantum dots. This technique will allow the fabrication of nanoscale atom optical devices. PACS. 03.75.Be...
