When optical components are reduced to the nanoscale, they exhibit interesting properties that can be harnessed to create new devices. For example, imagine a block of material with thin layers of alternating materials. This creates a periodic arrangement of alternating dielectric constants, forming a "photonic crystal" that is analogous to the electronic crystals used in semiconductor devices. Photonic crystals, along with quantum dots and other devices patterned at the nanoscale, may form the basis for sensors and switches used in computers and telecommunications.

Optical Signal Processing of Broadband Entangled Photons
03 Nov 2016 | | Contributor(s):: Ogaga Daniel Odele
Over the last few years, our group has been involved in developing novel techniques for controlling the correlations of broadband time-frequency entangled photons (“biphotons”) using classical optical-signal processing techniques. We believe our manipulation schemes will become...
Optical Hyperspace: Light in Metamaterials with Hyperbolic Dispersion
03 Nov 2016 | | Contributor(s):: Evgenii Narimanov
The composites with opposite signs of the dielectric permittivity in two orthogonal directions, known as the hyperbolic metamaterials, represent a new "universality class" of optical media, with the light behavior which is qualitatively different from that in either metals or...

Quantum Measurement Backaction: From Atoms to Optomechanics
13 Oct 2016 | | Contributor(s):: Mukund Vengalattore
The act of measurement has profound consequences on a quantum system. As such, the evolution of a quantum system can be influenced and even controlled through the continuous measurement of its properties. I will describe our studies on such measurement-induced dynamics in systems ranging from...
Coupling of Quantum Emitters to Localized and Propagating Plasmons
13 Oct 2016 | | Contributor(s):: Sergey I. Bozhevolnyi
In this talk, I review our latest theoretical and experimental results concerning QE coupling to localized and propagating SP modes. In particular, influence of gap SP resonators on the decay rate of closely located QEs and different decay contributions are discussed as well as the dynamics of...
Surprising Nanophotonic Phenomena in Nature and Photonic Modeling with S4
17 Aug 2016 | | Contributor(s):: Peter Bermel
I will show how S4sim, a transfer matrix-based optical simulation tool available on nanoHUB.org can be used to precisely calculate these behaviors. A few exciting real-world applications of this work will also be briefly discussed.
Surprising Nanophotonic Phenomena in Nature
11 Jul 2016 | | Contributor(s):: Peter Bermel
A broad range of optical phenomena in nature have created long-standing mysteries. For example, what gives butterflies and birds their rich colors? And how can sightings of some unusual natural phenomena like mirages or ball lightning be explained? The process of solving these mysteries has...
Computational Nanophotonics – Designing Spaces for Light
29 Jun 2016 | | Contributor(s):: Alexander V. Kildishev
In this presentation, after a brief review of previous work based on the innovative methods of transformation optics, I present a new class of elliptic omnidirectional concentrators focusing light on a disk, a thin strip, or a rod. This study expands the theory of a circular omnidirectional...
