Manipulating the properties of the isofrequency contours (IFCs) of materials provides a
powerful means of controlling the interaction between light and matter. Hyperbolic …

Metamaterials are effectively homogeneous materials that display extraordinary dispersion.
Negative index metamaterials, zero index metamaterials and extremely anisotropic …

With the rapid advance of integrated optics, the importance of optical waveguides, which are
the fundamental elements of optical integrated circuits, has been widely recognized. For …

We show that optical beams propagating in path-averaged zero-index photonic crystal
superlattices can have zero phase delay. The nanofabricated superlattices consist of …

Here, we present a mechanism for tailoring the photonic band structure of a quarter-wave
stack without changing its physical periods by embedding conductive sheets. Graphene is …

Controlling the flow of light at subwavelength scales provides access to functionalities such
as negative or zero index of refraction, transformation optics, cloaking, metamaterials and …

We theoretically study dispersionless gaps and cavity modes in one-dimensional photonic
crystals composed of hyperbolic metamaterials and dielectric. Bragg gaps in conventional …

On-chip channelless diffraction-free beam guiding enables dense integration of optical
circuits in a reconfigurable manner, where total internal reflection, which is considered the …

We present a comprehensive theoretical study of the second harmonic generation (SHG) in
metamaterials consisting of arbitrary distributions of cylindrical nanowires made of …

We address the topological properties of one-dimensional plasmonic superlattices
composed of alternating metallic and dielectric layers. We reveal that the Zak phase of such …
