Abruptly autofocusing wavesNikolaos K Efremidis
Department of Applied Mathematics, University of Crete, 71409 Heraklion, Crete, Greece
Opt Lett 35:4045-7. 2010
..These waves can be generated through the use of radially symmetric Airy waves or by appropriately superimposing Airy wave packets. Possible applications of such abruptly focusing beams are also discussed...
Airy trajectory engineering in dynamic linear index potentialsNikolaos K Efremidis
Department of Applied Mathematics, University of Crete, 71409 Heraklion, Crete, Greece
Opt Lett 36:3006-8. 2011

Caustic design in periodic latticesNikolaos K Efremidis
Department of Applied Mathematics, University of Crete, 71409 Heraklion, Crete, Greece
Opt Lett 37:1277-9. 2012
..More important, we find that by designing the initial phase or wavefront of the beam we can construct trajectories with pure power law caustics as well as aberration-free focusing of discrete waves...

Pre-engineered abruptly autofocusing beamsIoannis Chremmos
Archimedes Center for Modeling, Analysis and Computation ACMAC, Department of Applied Mathematics, University of Crete, Heraklion 71409, Crete, Greece
Opt Lett 36:1890-2. 2011
..The collapse of the caustic on the axis leads to a large intensity buildup right before the intended focus. This ray-optics interpretation provides valuable insight into the dynamics of abruptly autofocusing waves...
