Holographic recording and micro/nanofabrication via ultrafast holographic two-photon induced photopolymerization (H-TPIP)

The preferred embodiments of the present invention relate to a process of two-photon induced photopolymerization for the formation of microstructures. More particularly, the preferred embodiments of the present invention relate to holographic two-photon induced photopolymerization ("H-TPIP") in the construction of reflection and transmission holograms. A process and photoactive media for holographic recording and micro/nanofabrication of optical and bio-optical structures via the simultaneous absorption of two-photons by the photoactive media to induce a simultaneous photochemical change in regions of constructive interference within a holographic pattern is disclosed. The photochemical process of polymerization resulting from the simultaneous absorption of two-photons may be used for the microfabrication of micro and nanoscaled features, holographic data storage, and the formation of switchable diffraction gratings.
