title: MRT letter: Two-photon excitation-based 2pi light-sheet system for nano-lithography.
abstract: We propose two-photon excitation-based light-sheet technique for nano-lithography. The system consists of 2π-configured cylindrical lens system with a common geometrical focus. Upon superposition, the phase-matched counter-propagating light-sheets result in the generation of identical and equi spaced nano-bump pattern. Study shows a feature size of as small as few tens of nanometers with a inter-bump distance of few hundred nanometers. This technique overcomes some of the limitations of existing nano-lithography techniques, thereby, may pave the way for mass-production of nano-structures. Potential applications can also be found in optical microscopy, plasmonics, and nano-electronics.
