08:30 Keynote talk: Field- and Carrier-Enabled Nonlinear Nanophotonics
Wenshan Cai
Georgia Institute of Technology (USA)
The active manipulation of optical properties via external stimuli and the nonlinear wave-mixing of light with controlled means are among compelling research directions in nanophotonics. In this talk, we explore active and nonlinear plasmonic metamaterials by leveraging the field-induced disruption of the inversion symmetry for second-order optical processes, and exploiting the hot-carrier-induced perturbation in structured optical media for ultrafast all-optical modulation and nonlinear signal generation.

09:00 Keynote talk: Building Uncooled Infrared Camera based on One Atom Thick Graphene
Debashis Chanda
University of Central Florida (USA)
One atom thick graphene offers an alternative mechanism bypassing material bandgap restriction. Further, the ability of carrier concentration modulation on graphene via external voltage offers dynamic spectral selectivity for color night vision/sensing.

Nanostructures can be exploited to enhance nonlinear optical processes via the strong light confinement by their resonant modes. The dependence of these modes on the geometry and material composition offers ample opportunities for tailoring the optical response of the system. I report about sum-frequency generation (SFG) by individual dielectric and plasmonic nanocylinders, pumped by two pulsed beams with different photon energies. A rich size- and polarization-dependent behavior is observed, disclosing strategies to manipulate the nonlinear properties of nanoscale systems

We shall present an overview of our recent investigations into the time-dependent effects observed in transparent conductive oxides photoexcited at the epsilon near zero point. We will then discuss the role of the epsilon-near-zero mode in establishing the temporal dynamics in strongly coupled plasmonic systems.

10:10 Invited talk: Scalable quantum dot single-photon sources
Leonardo Midolo
University of Copenhagen (Denmark)
Deterministic sources of single photons are key elements for quantum information processing, simulation, and computing. I will present a photonic integrated circuit based on dual-mode waveguides for the resonant excitation of two self-assembled InAs quantum dots, paving the way to the integration of multiple sources on a chip. Our plug-and-play waveguide-based source can generate streams of pure and indistinguishable single photons on-demand, so that a planar platform for quantum photonic integrated circuits can be realized.
