Observation of microscale nonparaxial optical bottle beams
Raluca-Sorina Penciu, Yujie Qiu, Michael Goutsoulas +5
We predict and experimentally observe three-dimensional microscale nonparaxial optical bottle beams based on the generation of a caustic surface under revolution. Such bottle beams…
Independent amplitude and trajectory/beam-width control of nonparaxial beams
Michael Goutsoulas, Raluca-Sorina Penciu, Nikolaos K. Efremidis
We show that it is possible to generate non-paraxial optical beams with pre-engineered trajectories and designed maximum amplitude along these trajectories. The independent control…
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…
Closed-form expressions for nonparaxial accelerating beams with pre-engineered trajectories
Raluca-Sorina Penciu, Vassilis Paltoglou, Nikolaos K. Efremidis
In this letter, we propose a general real-space method for the generation of nonparaxial accelerating beams with arbitrary predefined convex trajectories. Our results lead to close…
