In optical microscopy and lithography, the resolution is restricted to about half the wavelength of the light by something called the diffraction limit. Many attempts have been made to advance this field beyond the current limit set by the wavelength of the laser used. These methods are usually based on multi-photon processes, multiple beams and/or quantum entanglement making the implementation of these schemes extremely difficult. In this talk, I shall discuss these methods and then present simple methods for optical sub-wavelength imaging and lithography.
