Carbon Nanotubes in a Photonic Metamaterial [PDF]

open access: yesPhysical Review Letters, 2010
Hybridization of single-walled carbon nanotubes with plasmonic metamaterials leads to photonic media with an exceptionally strong ultrafast nonlinearity. This behavior is underpinned by strong coupling of the nanotube excitonic response to the weakly radiating Fano-type resonant plasmonic modes that can be tailored by metamaterial design.

Spatio-temporal characterization of ultrashort vector pulses

open access: yesAPL Photonics, 2021
Ultrafast vectorially polarized pulses have found many applications in information and energy transfer owing mainly to the presence of strong longitudinal components and their space-polarization non-separability.

Plasmonic anapole metamaterial for refractive index sensing

open access: yesPhotoniX, 2022
Electromagnetic anapole mode is a nonradiative state of light originating from the deconstructive interference of radiation of the oscillating electric and toroidal dipole moments.

Non-contact optical magnetic field sensor based on metamaterial nanomechanics

open access: yesAPL Photonics, 2022
We demonstrate a non-contact optical magnetic field sensor that is based on actuation of a metamaterial-microcavity by the magnetic Lorentz force. Magnetic field is transduced to a change of the sensor’s reflectivity.

Asymptotics for metamaterials and photonic crystals [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2013
Metamaterial and photonic crystal structures are central to modern optics and are typically created from multiple elementary repeating cells. We demonstrate how one replaces such structures asymptotically by a continuum, and therefore by a set of equations, that captures the behaviour of potentially high-frequency waves propagating through a periodic ...

Second harmonic generation in amorphous silicon-on-silica metamaterial

open access: yesAPL Photonics, 2021
We demonstrate second harmonic generation by using an amorphous silicon metamaterial fabricated on the tip of an optical fiber that collects the generated light.

Reconfigurable nanomechanical photonic metamaterials [PDF]

open access: yesNature Nanotechnology, 2016
The changing balance of forces at the nanoscale offers the opportunity to develop a new generation of spatially reconfigurable nanomembrane metamaterials in which electromagnetic Coulomb, Lorentz and Ampère forces, as well as thermal stimulation and optical signals, can be engaged to dynamically change their optical properties.

Microwatt Volatile Optical Bistability via Nanomechanical Nonlinearity

open access: yesAdvanced Science, 2023
Metastable optically controlled devices (optical flip‐flops) are needed in data storage, signal processing, and displays. Although nonvolatile memory relying on phase transitions in chalcogenide glasses has been widely used for optical data storage ...

Optical magnetic response without metamaterials

open access: yesAPL Photonics, 2021
One of the main achievements of metamaterials research has been the development of structured matter exhibiting optical magnetism: first, in an array of microwave split-ring resonators and, soon after, in plasmonic and dielectric metamaterials at THz to ...
