- Linear and nonlinear waves in surface and wedge index potentialsNikolaos K Efremidis

Department of Applied Mathematics, University of Crete, 71409, Heraklion, Crete, Greece*Opt Lett*37:1874-6. 2012..The total power of such nonlinear waves is finite without the need for apodization... - Two-dimensional disordered lattice solitonsNikolaos K Efremidis

Department of Applied Mathematics, University of Crete, Heraklion, Crete, Greece*Opt Lett*34:596-8. 2009..In addition, families of highly confined solitons exist in every waveguide of the lattice and for both signs of the nonlinearity... - 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..More important, we find that the Airy beam can follow any predefined path, in which case the potential gradient is determined as a function of this path... - 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... - Bessel-like optical beams with arbitrary trajectoriesIoannis D Chremmos

Department of Applied Mathematics, University of Crete, Heraklion 71409, Greece*Opt Lett*37:5003-5. 2012..Such beams can be useful as hybrids between non-accelerating and accelerating optical waves that share diffraction-resisting and self-healing properties... - Fourier-space generation of abruptly autofocusing beams and optical bottle beamsIoannis Chremmos

Department of Applied Mathematics, University of Crete, Heraklion, Crete, Greece*Opt Lett*36:3675-7. 2011.... - Observation of abruptly autofocusing wavesDimitrios G Papazoglou

Institute of Electronic Structure and Laser, Foundation for Research and Technology Hellas, P O Box 1527, 71110, Heraklion, Greece*Opt Lett*36:1842-4. 2011..As demonstrated in our experiments, these waves can exhibit unusual features, such as the ability to autofocus by following a parabolic trajectory toward their focus... - Reflection and refraction of an Airy beam at a dielectric interfaceIoannis D Chremmos

Department of Applied Mathematics, University of Crete, Heraklion, Greece*J Opt Soc Am A Opt Image Sci Vis*29:861-8. 2012..We finally consider reverse refraction and perfect imaging of an Airy beam into a left-handed medium... - 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...
