Postdoc position on nonlinear light dynamics in the ERC project titled "Nonlinear Laser Lithography"
Please note that the job is no longer active!
We are looking for an experienced experimentalist with a strong theoretical background. Relevant background can be based on several different specialty areas, such as optical holography, holographic microscopy, nonlinear optical spatial pattern formation or nonlinear guided waves. Hands-on experience with spatial light modulator-based beam shaping would be strongly desirable. This position is funded through the ERC Consolidator Grant "Nonlinear Laser Lithography".

Synopsis of the ERC Project "Nonlinear Laser Lithography, NLL"
Control of matter via light has always fascinated humankind; not surprisingly, laser patterning of materials is as old as the history of the laser. Funded by an ERC Consolidator Grant, we aim to develop hitherto unimaginable levels of control over matter via laser light: laser-controlled self-assembly of plethora of 2D patterns, periodic, aperiodic and non-periodic, composed of a virtually endless variety of materials, eventually assembled layer by layer into the third dimension - a 3D material synthesizer. As preliminary results, we demonstrated self-organised formation of metal-oxide nanostructures, achieving unprecedented levels of uniformity over indefinitely large areas by simply scanning the laser beam over the surface [*].

Will focus on extending the NLL technique to creation of non-periodic, dynamically evolving structures through advanced control of the laser beam and of the nonlinear laser-material interactions. In NLL, the total optical field at any point is determined by the incident laser field and the scattered light from the surrounding surface, in a mathematical form similar to that of a hologram. Thus, it is only logical to control the self-organized pattern through the laser field using, e.g., a spatial light modulator. A simple wavefront tilt should change the periodicity of the nanostructures, but much more exciting possibilities include creation of patterns without translational symmetry, or patterns evolving non-trivially under scanning, and effectively performing computation, akin to cellular automata.
