Observation of light localization in modulated Bessel optical lattices
, 2015 We generate higher-order azimuthally modulated Bessel optical lattices in photorefractive crystals by employing a phase-imprinting technique. We report on the experimental observation of self-trapping and nonlinear localization of light in such ...

Characterisation of a three-dimensional Brownian motor in optical lattices
, 2007 We present here a detailed study of the behaviour of a three dimensional Brownian motor based on cold atoms in a double optical lattice [P. Sjölund et al., Phys. Rev. Lett. 96, 190602 (2006)]. This includes both experiments and numerical simulations of a

Modulational instability of Bose-Einstein condensates in two- and three-dimensional optical lattices
, 2002 We show that the phenomenon of modulational instability gives rise to coherent spatial structures in arrays of Bose-Einstein condensates confined in optical lattices.

Programming an optical lattice interferometer
Materials Today QuantumProgramming a quantum device describes the usage of quantum logic gates, agnostic of hardware specifics, to perform a sequence of operations with (typically) a computing or sensing task in mind. Such programs have been executed on digital quantum computers, which despite their noisy character, have shown the ability to optimize metrological functions ...

Evaluation of the Scintillation Loss for Optical Communication Systems with Direct Detection [PDF]
, 2006 In optical communications through the atmosphere, the evaluation of a link feasibility often requires the quantification of the scintillation penalty in terms of power loss. To find how much additional optical power is needed to reach the bit-error-rate (

Beam dynamics in optical mesh lattices
, 2013 We study propagation dynamics in a new class of optical lattices which are bi-periodic and discrete in both coordinates. These mesh structures exhibit peculiar linear and nonlinear properties which are unattainable in traditional optical lattices.

Optical quasisymmetry groups for meron lattices
Physical Review ResearchWe report that optical quasisymmetry groups emerge from the commutation between mirror operation and spin-orbit interaction (SOI) of light. Contrary to the principle of symmetry inheritance in free-space optics—where the symmetry of any structured field ...
