Manipulating Gradient Forces on Optical Tweezers using Bessel Beams
Leonardo A. Ambrosio, Michel Zamboni-Rached, Hugo E. Hernández-Figueroa
In this paper, we show how one can change the stable equilibrium of a particle trapped into an optical tweezer by varying the intensity of superposed Bessel beams with different or…
Axicons in FSO Systems
Leonardo A. Ambrosio, Michel Zamboni-Rached, Hugo E. Hernández-Figueroa
This paper studies the possibility of using axicons in Free Space Optics (FSO) systems. The behavior of the pseudo- Bessel beams generated by "logarithmic" and "linear" axicons, wi…
Diffraction-Attenuation Resistant Beams: their Higher Order Versions and Finite-Aperture Generations
Michel Zamboni-Rached, Leonardo André Ambrósio, Hugo Hernández Figueroa
Recently, a method for obtaining diffraction-attenuation resistant beams in absorbing media was developed through suitable superposition of ideal zero-order Bessel beams. In this w…
Multi-wavelength source at ITU-T grid based on ultra-flattened dispersion photonic crystal fibers
Arismar Cerqueira S., J. D. Marconi, L. H. Gabrielli +4
We report on the development of a multi-wavelength source locked to the ITU-T grid at 100 GHz spacing and based on ultra-flattened dispersion photonic crystal fibers. The ITU-T gri…
Theory of Frozen Waves
M. Zamboni-Rached, E. Recami, H. E. Hernandez-Figueroa
In this work, starting by suitable superpositions of equal-frequency Bessel beams, we develop a theoretical and experimental methodology to obtain localized stationary wave fields,…
Chirped optical X-shaped pulses in material media
Michel Zamboni-Rached, Hugo E. Hernandez-Figueroa, Erasmo Recami
In this paper we analyze the properties of chirped optical X-shaped pulses propagating in material media without boundaries. We show that such ("superluminal") pulses may recover t…
