Nonlinear imaging in photonic lattices
Nikolaos K. Efremidis, Mihalis Mparkas
We show that nonlinear imaging is possible in periodic waveguide configurations provided that we use two different segments of nonlinear media with opposite signs of the Kerr nonli…
Parity breaking with a nonlinear optical double-slit configuration
Vassilis Paltoglou, Nikolaos K. Efremidis
We consider an optical nonlinear interferometric setup based on Young's double-slit configuration where a nonlinear material is placed exactly after one of the two slits. We examin…
Nonparaxial abruptly autofocusing beams
Raluca-Sorina Penciu, Konstantinos G. Makris, Nikolaos K. Efremidis
We study nonparaxial autofocusing beams with pre-engineered trajectories. We consider the case of linearly polarized electric optical beams and examine their focusing properties su…
