Microscopies Enabled by Photonic Metamaterials [PDF]
In recent years, the biosensor research community has made rapid progress in the development of nanostructured materials capable of amplifying the interaction between light and biological matter. A common objective is to concentrate the electromagnetic energy associated with light into nanometer-scale volumes that, in many cases, can extend below the ...

Reconfigurable Photonic Metamaterials [PDF]
We introduce mechanically reconfigurable photonic metamaterials (RPMs) as a flexible platform for realizing metamaterial devices with reversible and large-range tunable characteristics in the optical part of the spectrum. Here we illustrate this concept for a temperature-driven RPM exhibiting reversible relative transmission changes of up to 50%.

The Magical World of Photonic Metamaterials [PDF]
Metamaterials have opened a world of new possibilities that would have seemed like science fiction a decade ago, including subwavelength imaging, super lenses, perfect lenses and cloaking.

Photonic Bandgaps of One-Dimensional Photonic Crystals Containing Anisotropic Chiral Metamaterials
Conventional photonic bandgaps (PBGs) for linear polarization waves strongly depend on the incident angle. Usually, PBGs will shift toward short wavelengths (i.e., blue-shifted gaps) as the incident angle increases, which limits their applications.

Abnormal Angle-Dependent Multi-Channel Filtering in Photonic Crystals Containing Hyperbolic Metamaterials [PDF]
Tunneling modes in all-dielectric one-dimensional photonic crystals can be utilized for multi-channel filtering. However, these tunneling modes generally blue shift upon increasing the incident angle. When hyperbolic metamaterials are introduced into one-

Photonic crystals and metamaterials
Recent results obtained on semiconductor-based photonic crystal devices are of great promise for future developments of photonic crystals and their applications to ‘all-photonic’ integrated circuits. Device performance mostly relies on the strong confinement of light thanks to photonic bandgap effects, but photonic crystals also exhibit remarkable ...

Supertoroidal light pulses as electromagnetic skyrmions propagating in free space
Topology in electromagnetic fields can lead to a range of intriguing and unexpected phenomena. Here the authors describe a family of supertoroidal light pulses that exhibit skyrmionic topological structure flying in free space.

Chiral Photonic Metamaterial [PDF]
We demonstrate novel chiral photonic metamaterials consisting of physically separated mutually twisted planar metal patterns in parallel planes. Such metamaterials are shown to exhibit very strong gyrotropy (600°/mm) in the visible, near-IR and microwaves.

Toy model of harmonic and sum frequency generation in 2D dielectric nanostructures
Optical nonlinearities of matter are often associated with the response of individual atoms. Here, using a toy oscillator model, we show that in the confined geometry of a two-dimensional dielectric nanoparticle a collective nonlinear response of the ...
