Photonic Nanostructures

Historically, optical lithography was considered to be limited by the Abbe diffraction barrier, which lead to the belief that no grating much smaller than half the wavelength of light could be fabricated. With demonstration of the stimulated emission depletion (STED) mechanism, it is now feasible to break this barrier.

At the INT, by combining STED ideas with direct laser writing (DLW), we can produce photonic crystals with band gaps at visible frequencies. We are also working on integrating nanomechnical elements with optical elements on a single chip, which could be useful for future telecommunication devices.
