Observation of edge solitons in topological trimer arrays
(American Institute of Physics (AIP), 2022-03-04)
Article
Open AccessWe report the experimental observation of nonlinear light localization and edge soliton formation at the edges of fs-laser written trimer waveguide arrays, where transition from nontopological to topological phases is ... -
Unidirectional guided resonances in anisotropic waveguides
(2021-05-15)
Article
Open AccessWe show that anisotropic planar anti-guiding waveguide structures with two radiation channels toward the surrounding cladding materials can support unidirectional guided resonances (UGRs), where radiation is canceled in ... -
Slow light mediated by mode topological transitions in hyperbolic waveguides
(2021-01-01)
Article
Open AccessWe show that slow light in hyperbolic waveguides is linked to topological transitions in the dispersion diagram as the film thickness changes. The effect appears in symmetric planar structures with type II films, whose ... -
Quantum holography with undetected light
(2022-01-14)
Article
Open AccessHolography exploits the interference of a light field reflected/transmitted from an object with a reference beam to obtain a reconstruction of the spatial shape of the object. Classical holography techniques have been very ... -
Floquet edge multicolor solitons
(John Wiley & sons, 2022-03)
Article
Open AccessTopological insulators are unique physical structures that are insulators in their bulk, but support currents at their edges which can be unidirectional and topologically protected from scattering on disorder and ... -
Multifrequency solitons in commensurate-incommensurate photonic moiré lattices
(American Institute of Physics (AIP), 2021-10-15)
Article
Open AccessWe predict that photonic moiré patterns created by two mutually twisted periodic sublattices in quadratic nonlinear media allow the formation of parametric solitons under conditions that are strongly impacted by the geometry ... -
Topological dipole Floquet solitons
(American Physical Society, 2021-05-11)
Article
Open AccessWe theoretically introduce a type of topological dipole soliton propagating in a Floquet topological insulator based on a kagome array of helical waveguides. Such solitons bifurcate from two edge states belonging to different ... -
Reversible self-replication of spatiotemporal Kerr cavity patterns
(American Institute of Physics (AIP), 2021-02-12)
Article
Open AccessWe uncover a novel and robust phenomenon that causes the gradual self-replication of spatiotemporal Kerr cavity patterns in cylindrical microresonators. These patterns are inherently synchronized multifrequency combs. Under ... -
Quantum-inspired Fredkin gate based on spatial modes of light
(2020-04-27)
Article
Open AccessInsights gained from quantum physics can inspire novel classical technologies. These quantum-inspired technologies are protocols that aim at mimicking particular features of quantum algorithms. They are generally easier ... -
Optical coherence tomography with a nonlinear interferometer in the high parametric gain regime
(2020-08-31)
Article
Open AccessWe demonstrate optical coherence tomography based on an SU(1,1) nonlinear interferometer with high-gain parametric down-conversion. For imaging and sensing applications, this scheme promises to outperform previous experiments ... -
Frequency-correlation requirements on the biphoton wave function in an induced-coherence experiment between separate sources
(American Physical Society, 2020-11-11)
Article
Open AccessThere is renewed interest in using the coherence between beams generated in separate down- converter sources for new applications in imaging, spectroscopy, microscopy and optical coherence tomography (OCT). These schemes ... -
Nonlinearity-induced photonic topological insulator
(2020-11-06)
Article
Open AccessA hallmark feature of topological insulators is robust edge transport that is impervious to scattering at defects and lattice disorder. We demonstrate a topological system, using a photonic platform, in which the existence ...
