Abstract

In this work, we investigated the absorption of light in perovskite nanowires (PrvNWs) for application as active layer in a solar cell. Specifically, we simulated PrvNWs with a random position inside the pores of an AAO membrane. The results demonstrate that this vertical disorder can boost light absorption, up to 28% in terms of short-circuit current, in comparison to the corresponding ordered PrvNW array. This performance boost is due to a combination of light trapping and anti-reflection effect. Thus, our findings suggest that vertically disordered PrvNWs can have a much better performance than ordered arrays. Also, we showed that it is not necessary to aim for a very narrow length distribution in the nanowires, easing the fabrication requirements.

Plasmonic Metasurfaces for Magnetic Skyrmion Control via the Inverse Faraday Effect

Magnetic skyrmions hold immense promise for low-power spintronic memory, logic devices, and neuromorphic computing. However, existing optical and electrical manipulation schemes rely predominantly on local thermal excitation, rendering skyrmion nucleation inherently stochastic and lacking a non-destructive mechanism for targeted, on-demand erasure. Here, we demonstrate a deterministic, field-driven paradigm for the ultrafast, all-optical writing and erasing of magnetic skyrmion crystals using a magneto-plasmonic metasurface. By tailoring surface lattice resonances in a periodic nanodisk array, circularly polarized light excites giant super-circular optical spin densities that drive intense circulating drift photocurrents via the inverse Faraday effect, delivering synchronized picosecond magnetic field pulses directly to an adjacent chiral magnetic multilayer. Micromagnetic simulations reveal that a single optical pulse deterministically nucleates stable Neel skyrmions through a transient Bloch to Neel relaxation pathway governed by optical helicity and interfacial Dzyaloshinskii Moriya interaction. Crucially, reversing the incident light helicity allows on-demand reconfiguration of the topological state under a confining bias field, the inverted optomagnetic field unwinds pre-existing skyrmions to restore the uniform ground state, whereas at zero field it deterministically transforms an expanded skyrmion into a stable skyrmionium. By bypassing stochastic thermal cycles and achieving fully reversible topological control on picosecond timescales, this work bridges nanophotonics and magnetism, establishing a scalable foundation for high-speed, reconfigurable topological data storage and unconventional computing architectures.

Hopping of nanoparticles in optical tweezers governed by Mie resonances

Optical tweezers have become a standard tool for manipulating microscale and nanoscale particles and probing their local environments. However, complex particle dynamics under optical forces typically require structured light fields, multi-beam traps, or engineered environments. Here we achieve complex particle dynamics in a single Gaussian-beam optical tweezer. The effect originates from higher-order Mie resonances supported by wavelength-scale particles. In our optical tweezer, small particles in the regime of Rayleigh scattering or the lowest-order dipole-type Mie modes remain confined at the beam center. By contrast, particles within the range of sizes corresponding to quadrupole-type Mie modes exhibit more complex behavior. In a linearly polarized Gaussian beam, these particles are trapped in a potential with two off-axis equilibria. We observe thermally driven hopping between these equilibria, with the hopping frequency controlled by the laser power. In a circularly polarized Gaussian beam, the particles are confined to a stable orbit and exhibit circular motion driven by the spin (circular-polarization) degree of freedom of the beam, with angular velocity dependent on the laser power. These results reveal higher-order Mie resonances as an intrinsic mechanism behind complex optical forces. This establishes Mie-resonant nanophotonics as a flexible platform for inducing and controlling complex motion in optical tweezers for nanoparticle manipulation as well as sensing of local environments.

Toward triggered generation of indistinguishable single-photons from MoTe$_2$ quantum emitters

Single-photon sources operating at telecom wavelengths are fundamental components for long-distance optical quantum communication and information processing. Two-dimensional (2D) transition metal dichalcogenides (TMDs) offer a promising platform for such sources, but their development has been hindered by limited spectral range and poor single-photon indistinguishability. Here, we demonstrate a reproducible and systematic approach for generating near-infrared (1090-1200 nm) quantum emitters in bilayer MoTe$_2$ using deterministic strain and defect engineering. These emitters exhibit strong linear polarization (DOLP $>70%$), sub-nanosecond lifetimes ($τ\sim$ 130-450 ps), high single-photon purity with triggered $g^{(2)}(0)$ values as low as $\sim$0.01 ($\sim$0.16) under p-shell (quasi-resonant) excitation, and resolution-limited emission ($\sim$150 $μ$eV). Electrostatic biasing enables tuning over a $\sim$3 meV range, suppresses photon bunching, and significantly shortens radiative lifetimes, yielding narrow emission with ratios of experimental to transform-limited linewidths as low as $R\sim55$. Most notably, two-photon interference measurements reveal a Hong-Ou-Mandel visibility of $V_{HOM}\sim$ 7.1$%$ (3.6$%$), and up to $V_{HOM}\sim$ 60$%$ ($\sim$40$%$) with post-selection by temporal filtering under p-shell (quasi-resonant) excitation. To our knowledge, this presents the highest reported indistinguishability for TMD quantum emitters and the first such demonstration for MoTe$_2$ platform. These results establish MoTe$_2$ as a viable platform for tunable, low-noise, high-purity single-photon sources with state-of-the-art indistinguishability for TMD quantum emitters, paving the way for their integration into telecom-compatible quantum photonic technologies.
