Nonlinear optics are expected to play a major role in the technology of photonics, which is d of electrons, are used to acquire, store, transmit, and process information. Examples of nonlinear optical phenomena that are potentially useful are; the ability to alter the frequency (or color) of light; to amplify one source of light with another; to switch or alter the transmission characteristics of light through a medium depending on its intensity, which can find their applications in 3D optical data storage, 3D optical imaging for biological systems and early corrosion detection, optical power limiting, and photodynamic therapy. Furthermore, a photonic switch can produce flips at femtosecond speed, thus providing a gain in speed that is many orders of magnitude over that of electronic processes. Response theory has been developed and applied for calculations of the second- and third- nonlinear optical properties of molecules, polymers and fullerenes.
