Spatial mode detection by frequency upconversion
(2019-02-01)
Article
Open AccessThe efficient creation and detection of spatial modes of light has become topical of late, driven by the need to increase photon bit-rates in classical and quantum communications. Such mode creation/detection is traditionally ... -
Topological properties of bound states in the continuum in geometries with broken anisotropy symmetry
(2018-12-18)
Article
Open AccessWaveguiding structures made of anisotropic media support bound states in the continuum (BICs) that arise when the radiation channel of otherwise semileaky modes is suppressed. Hitherto, only structures with optical axes ... -
Technique for generating periodic structured light beams using birefringent elements
(2018-10-29)
Article
Open AccessWe put forward a simple, scalable and robust technique for generating periodically structured light beams with intensity patterns, e.g. of the form cos2n(kxx) cos2m(kyy), where kx and ky are real numbers that can be tailored ... -
Inhibition of tunneling and edge state control in polariton topological insulators
(2018-12-01)
Article
Open AccessWe address the inhibition of tunneling in polariton condensates confined in a potential landscape created by a honeycomb array of microcavity pillars in the presence of spin- orbit coupling and Zeeman splitting in the ... -
Clusters of cavity solitons bounded by conical radiation
(American Institute of Physics (AIP), 2018-09-06)
Article
Open AccessWe introduce a new class of self-sustained states, which may exist as single solitons or form multisoliton clusters, in driven passive cylindrical microresonators. Remarkably, such states are stabilized by the radiation ... -
Three-dimensional droplets of swirling superfluids
(American Physical Society (APS), 2018-07-12)
Article
Open AccessA new method for the creation of 3D solitary topological modes, corresponding to vortical droplets of a two-component dilute superfluid, is presented. We use the recently introduced system of nonlinearly coupled Gross-Pitaevskii ... -
Space QUEST mission proposal: experimentally testing decoherence due to gravity
(2018-06-12)
Article
Open AccessModels of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum correlations, such as entanglement, may exhibit different behavior to purely classical ... -
Optical sectioning in induced coherence tomography with frequency-entangled photons
(American Physical Society, 2018-02-14)
Article
Open AccessWe demonstrate a different scheme to perform optical sectioning of a sample based on the concept of induced coherence [Zou et al., Phys. Rev. Lett. 67, 318 (1991)]. This can be viewed as a different type of optical coherence ... -

Cavity solitons in a microring dimer with gain and loss
(2018-02-20)
Article
Open AccessWe 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
Open AccessWe 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
Open AccessWe 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. ...
