Subdiffraction and spatial filtering due to periodic spatial modulation of the gain/loss profile
K. Staliunas, R. Herrero, R. Vilaseca
We investigate light propagation through materials with periodically modulated gain/loss profile in both transverse and longitudinal directions, i.e. in material with two-dimension…

Sub-Diffractive Band-Edge Solitons in Bose-Einstein Condensates in Periodic Potentials
Kestutis Staliunas, Ramon Herrero, German J. de Valcarcel
A new type of matter wave diffraction management is presented that leads to sub-diffractive soliton-like structures. The proposed management technique uses two counter-moving, iden…

Nondifractive Propagation of Light in Photonic Crystals
K. Staliunas, R. Herrero
We show that diffraction of electromagnetic radiation (in particular of a visible light) can disappear in propagation through materials with periodically in space modulated refract…
