We report the directed assembly of quantum dots (QDs) within well-ordered photonic nanocomposites using a family of (polynorbornene-graft-poly(styrene))-block-(polynorbornene-graft-poly(ethylene oxide)) (PS-b-PEO) brush block copolymers (BBCPs). Cadm

When engineered on scales much smaller than the operating wavelength, metal-semiconductor nanostructures exhibit properties unobtainable in nature. Namely, a uniaxial optical metamaterial described by a hyperbolic dispersion relation can simultaneous

We report the demonstration of luminescent hyperbolic metasurfaces (LuHMS) fabricated from deeply subwavelength multilayer metal-semiconductor nanostructures. The LuHMS exhibit extreme polarization anisotropy of absorption and emission, modified emis

Generalized Lotka–Volterra (GLV) equations are important equations used in various areas of science to describe competitive dynamics among a population of N interacting nodes in a network topology. In this Letter, we introduce a photonic network co

We propose modification to gain spectra of semiconductor quantum heterostructures by incorporation of nanostructured metal, paving the way for tailor made “meta-gain” media. We show that the wavelength dependence of the principal direction of ene

Here we present a brain-inspired photonic cognitive motif network. The proposed architecture consists of semiconductor lasers that are coupled through opto-electronic feedbacks. Competitive interaction among photons and carriers in these coupled lase

Hyperbolic metasurfaces (HMS) combine the potential for chip-scale integration of optical metasurfaces with the properties of hyperbolic dispersion. In the ideal, lossless effective medium limit, HMS have an unbound optical density of states (DOS). T

We fabricate and characterize a luminescent hyperbolic metamaterial consisting of InGaAsP/Ag multilayers. For the first time, one of the metamaterial constituents is a gain media. The hyperbolic dispersion is confirmed through the anisotropic photolu

We propose a new approach to solve optimization problems using Generalized Lotka-Volterra with global inhibition. Stability criteria ensure the convergences of valid solutions are obtained and the solution is given by the switching time of the networ
