Extreme Space-Time Optics & Quantum Meta-Photonics
Online Presentations | 16 Feb 2024 | Contributor(s):: Vladimir M. Shalaev
We first discuss all-optical modulation with single photons using electron avalanche, resulting in record-high nonlinearities. Then we show that transparent conducting oxides (TCOs) operating in the near-zero index (NZI) regime can provide strong single-cycle modulation, thus enabling novel...

Optical Hyperspace: Light in Hyperbolic Materials
Online Presentations | 14 Jan 2020 | Contributor(s):: Evgenii Narimanov
Hyperbolic metamaterias are strongly anisotropic composite media that behave as either metals or dielectrics in different directions. They can be fabricated n many different ways, such as metallic layers that are separated from each other by thin dielectric spacers, or using arrays of parallel...

Topological Materials as Platforms for New Particles and Electromagnetic Responses
Online Presentations | 06 Jun 2019 | Contributor(s):: Joel Moore
We then turn to how topological Weyl and Dirac semimetals can show unique electromagnetic responses; we argue that in linear response the main observable effect solves an old problem via the orbital moment of Bloch electrons, and how in nonlinear optics there should be a new quantized effect,...

Quantum Optics on a Nonlinear Chip
Online Presentations | 08 May 2018 | Contributor(s):: Alexander Solntsev
Bringing the concepts of quantum entanglement and optical nonlinearity together, and integrating them on a chip, opens a way to efficient generation of entangled photons and entanglement.

Coherent Nonlinear Optical Propagation Processes in Hyperbolic Metamaterials
Online Presentations | 08 Jun 2017 | Contributor(s):: Alexander K. Popov
Coherence and interference play an important role in classic and quantum physics. Processes to be employed can be significantly enhanced and the unwanted ones suppressed through the deliberately tailored constructive and destructed interference at quantum transitions and at nonlinear optical...

Negative Refraction, Wave-particle Dualism and “Minkowski-Abraham controversy”
Online Presentations | 19 Nov 2012 | Contributor(s):: Victor G. Veselago
Professor Veselago was the first to identify that the relationships between energy and linear momentum are significantly different for electromagnetic radiation and material particles. The process of transfer of radiation from the emitter to the receiver will be discussed. It is shown that the...

Taming Light and Electrons with Metamaterials
Online Presentations | 11 Jul 2011 | Contributor(s):: Nader Engheta
In recent years, in my group we have been working on various aspects of metamaterials and plasmonic nano-optics. We have introduced and been developing the concept of "metatronics", i.e. metamaterial-inspired optical nanocircuitry, in which the three fields of "electronics", "photonics" and...
