Conductance and current noise of a superconductor/ferromagnet quantum point contact
, 2008 We study the conductance and current noise of a superconductor/ferromagnet (S/F) single channel Quantum Point Contact (QPC) as a function of the QPC bias voltage, using a scattering approach.

Tunable Hybrid Fano Resonances in Halide Perovskite Nanoparticles.
Nano letters (Print), 2018 Halide perovskites are known to support excitons at room temperatures with high quantum yield of luminescence that make them attractive for all-dielectric resonant nanophotonics and meta-optics.

Laser &Photonics Reviews, EarlyView.Introducing dynamical dephasing into the photon modes of a waveguide causes spontaneous emission to switch from conventional exponential decay to a robust power‐law behavior visible at short times. The power law arises from photon diffusion in a dynamically disordered environment, uncovering a previously unexplored, decoherence‐induced pathway to ...

Widening of the large-angle half-wave wall through a pair of parameter-reversal Fano resonances
Materials & DesignWith the high quality (Q) factor, the Fano resonance has only been focused on sensing and switching, while its value in other fields ignored. In this manuscript, according to the Fano spectral characteristics, we have first proposed to use the Fano ...

Symmetry breaking with coupled Fano resonances
Optics Express, 2008 We describe the effect of symmetry breaking in a system with two coupled Fano resonators. A general criterion is derived and optimal parameter regions for switching are identified. By extending the single resonator behavior we show that one achieves the effect at very low input powers.

Photonic Systolic Array for All‐Optical Matrix–Matrix Multiplication
Laser &Photonics Reviews, EarlyView.A photonic systolic array is introduced, offering extreme parallelism in matrix‐matrix multiplication based on the synchronized movement of optical pulses along a crossbar array. Optical pulses traveling in perpendicular directions meet at freeform‐designed multiply‐accumulate units, each tailored to generate two signals whose intensity difference ...

Double Fano Resonances in S-Shaped Plasmonic Metasurfaces in Terahertz Region
Frontiers in Physics, 2020 We numerically and experimentally demonstrated double Fano resonances in a simple S-shaped plasmonic metasurface in the terahertz frequency range. Apart from the electric-LC resonance and electric dipole (ED) resonance, two trapped modes are excited in ...

Deep‐Subwavelength Coupling‐Induced Fano Resonances in Symmetric Terahertz Metamaterials
Physica Status Solidi (a), 2019 Fano resonances in metamaterials attract intense attention due to their sharp asymmetric spectral feature and low radiative loss channel. Typically, Fano resonances are excited in metamaterials with broken structural symmetry in a planar configuration ...

Mode‐Locked Pulse Generation in Plasmonic Lattices
Laser &Photonics Reviews, EarlyView.The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...
