Frequency conversion of structured light
(Macmillan Publishers, 2016-02-15)
Article.
Accés obert
Article.
Accés obert
Coherent frequency conversion of structured light, i.e. the ability to manipulate the carrier frequency of a wave front without distorting its spatial phase and intensity profile, provides the opportunity for numerous novel ...
Self-homodyne detection of the light orbital angular momentum

A simple optical system for the self-homodyne detection of the orbital angular momentum (OAM) carried by optical
beams is introduced. We propose two different schemes based on the use of optical hybrids, which could detect ...

The orbital angular momentum of light represents a fundamentally new optical degree of freedom. Unlike linear momentum, or spin angular momentum, which is associated with the polarization of light, orbital angular momentum ...
Highly efficient noise-assisted energy transport in classical oscillator systems
(2013-05)
Article.
Accés obert
Article.
Accés obert
Photosynthesis is a biological process that involves the highly-efficient transport of energy captured from the sun to a reaction center, where conversion into useful biochemical energy takes place. Even though one can ...
Engineerable generation of quadratic solitons in synthetic phase-matching

Article.
Accés restringit per política de l'editorial
We show that the efficiency and the mismatch bandwidth of quadratic soliton formation under conditions of second-harmonic generation can be enhanced in an important way in synthetic phase-matching profiles. Soliton excitation ...
Tandem light bullets

Article.
Accés restringit per política de l'editorial
We put forward a novel strategy to achieve formation of fully three-dimensional light bullets. The new scheme is based on tandem structures where nonlinearity and group-velocity dispersion required for the self-trapping ...
Gaussian-beam excitation of 3d nonlinear waves

Article.
Accés restringit per política de l'editorial
The propagation of stationary three-dimensional nonlinear guided waves and of Gaussian beams in a slab waveguide in which the cladding displays both Kerr-law and saturable instantaneous self-focusing nonlinearities is ...
A 3D printed toolbox for opto-mechanical components
(2017-01-18)
Article.
Accés obert
Article.
Accés obert
In this article we present the development of a set of opto-mechanical components (a kinematic mount, a translation stage and an integrating sphere) that can be easily built using a 3D printer based on Fused Filament ...
Nanostep height measurement via spatial mode projection
(2014-01-15)
Article.
Accés obert
Article.
Accés obert
We demonstrate an optical scheme for measuring the thickness of thin nanolayers with the use of light beam
’
s spa-
tial modes. The novelty in our scheme is the projection of the beam reflected by the sample onto a ...
Eigenvalue control and switching by fission of multisoliton bound states in planar waveguides

Article.
Accés restringit per política de l'editorial
Article.
Accés restringit per política de l'editorial
We report the results of numerical studies of the fission of ¿-soliton bound states at the interface formed by a Kerr nonlinear medium and a linear dielectric in a planar waveguide. A variety of effects are shown to occur, ...
