Nonlinear Optical Response of the GaAs Exciton Polariton
High-resolution differential optical transmission measurements of a thin layer of bulk GaAs show anomalous behavior of the lowest energy exciton at low excitation density and temperature. The spectrum shows induced absorption with a superlinear dependence on excitation density with no detectable change in resonance frequency or linewidth. At a temperature dependent excitation density, the anoma...
متن کاملExciton-polariton mediated superconductivity.
We revisit the exciton mechanism of superconductivity in the framework of microcavity physics, replacing virtual excitons as a binding agent of Cooper pairs by excitations of an exciton-polariton Bose-Einstein condensate. We consider a model microcavity where a quantum well with a two-dimensional electron gas is sandwiched between two undoped quantum wells, where a polariton condensate is forme...
متن کاملSimulation of an all Optical Time Division Multiplexing Router Employing
Synchronisation is an important and critical issue in high-speed all optical time division multiplexed (OTDM) packet routing and transmission. In this paper we present a technique for separating the clock synchronization pulse from an incoming optical time division multiplexed data packet, based on all-optical switching devices with optical feedback. A 1X2 OTDM router composed of three Symmetri...
متن کاملExciton-polariton emission from organic semiconductor optical waveguides
We photoexcite slab polymer waveguides doped with J-aggregating dye molecules and measure the leaky emission from strongly coupled waveguide exciton polariton modes at room temperature. We show that the momentum of the waveguide exciton polaritons can be controlled by modifying the thickness of the excitonic waveguide. Nonresonantly pumped excitons in the slab excitonic waveguide decay into tra...
متن کاملRealization of an all-dielectric zero-index optical metamaterial
Metamaterials offer unprecedented flexibility for manipulating the optical properties of matter, including the ability to access negative index1–4, ultrahigh index5 and chiral optical properties6–8. Recently, metamaterials with near-zero refractive index have attracted much attention9–13. Light inside such materials experiences no spatial phase change and extremely large phase velocity, propert...
