Cavity solitons in a microring dimer with gain and loss
(2018-02-20)
Article
Accés restringit per política de l'editorialWe address a pair of vertically coupled microring resonators with gain and loss pumped by a single-frequency field. Coupling between microrings results in a twofold splitting of the single microring resonance that increases ... -
Lieb polariton topological insulators
(American Physical Society, 2018-02-12)
Article
Accés obertWe predict that the interplay between the spin-orbit coupling, stemming from the transverse electric–transverse magnetic energy splitting, and the Zeeman effect in semiconductor microcavities supporting exciton-polariton ... -
Bound states in the continuum in a two-dimensional PT - symmetric system
(2018-02-01)
Article
Accés restringit per política de l'editorialWe address a 2D parity-time (¿¿)-symmetric structure built as a chain of waveguides, where all waveguides except for the central one are conservative, while the central one is divided into two halves with gain and losses. ... -
STED imaging performance estimation by means of Fourier transform analysis
(2017-05-01)
Article
Accés obertDue to relatively high powers used in STED, biological samples may be affected by the illumination in the process of image acquisition. Similarly, the performance of the system may be limited by the sample itself. Optimization ... -
Bound states in the continuum in spin-orbit-coupled atomic systems
(2017-09-14)
Article
Accés restringit per política de l'editorialWe show that the interplay between spin-orbit coupling and Zeeman splitting in atomic systems can lead to the existence of bound states in the continuum (BICs) supported by trapping potentials. Such states have energies ... -
Gap solitons on a ring
(2008-12)
Article
Accés restringit per política de l'editorialWe introduce a new species of gap solitons (GSs) supported by an azimuthally modulated guiding ring in defocusing cubic media. The periodicity in the azimuthal direction strongly modifies properties and existence domains ... -
Four-wave mixing of light beams with engineered orbital angular momentum in cold cesium atoms
(2004-07)
Article
Accés restringit per política de l'editorialWe report an experimental demonstration that shows that the spatial structure carried by engineered coherent superpositions of light beams with orbital angular momentum can be mapped into the nonlinear polarization induced ... -
Orbital angular momentum of entangled counterpropagating photons
(2004-08)
Article
Accés restringit per política de l'editorialWe elucidate the paraxial orbital angular momentum of entangled photon pairs generated by spontaneous parametric downconversion in different noncollinear geometries in which the entangled photons counterpropagate. We find, ... -
Soliton eigenvalue control in optical lattices
(2004-09)
Article
Accés restringit per política de l'editorialWe address the dynamics of higher-order solitons in optical lattices, and predict their self-splitting into the set of their single-soliton constituents. The splitting is induced by the potential introduced by the lattice, ... -
Second harmonic generation tuning curves in quasiphase-matched potassium titanyl phosphate with narrow, high-intensity beams
(American Institute of Physics (AIP), 2003-06)
Article
Accés restringit per política de l'editorialThe second harmonic generation (SHG) tuning curves with temperature and angle of incidence were measured in periodically poled KTiOPO4 for narrow fundamental beams at intensities typical of quadratic soliton generation. ... -
Observation of optical vortex streets in walking-second harmonic generation
(2002-04-15)
Article
Accés restringit per política de l'editorialWe report what is believed to be the first experimental observation of spontaneous nucleation of arrays of optical vortices in the process of second-harmonic generation in a crystal with moderate Poynting vector walk-off, ... -
Continuous-wave self-pumped optical parametric oscillator based on Yb3+-doped bulk periodically-poled LiNbO3 (Mg0)
(2001-05-15)
Article
Accés restringit per política de l'editorialWe present experimental evidence of continuous-wave self-pumped parametric oscillation in Yb3+-doped periodically poled lithium niobate co-doped with MgO. A single bulk crystal of periodically poled lithium niobate containing ...
