Advances in Hybrid Plasmonics II

14:00 Invited talk : Controlling absorption with nanophotonics: application to solar energy conversion and plasmon rulers

Vivian Ferry

University of Minnesota (USA)

This talk will discuss our efforts in nanophotonics for enhancement of solar cell performance. The first part will focus on the integration of photonics with narrow band quantum dot light emitters to achieve high concentration ratios in luminescent solar concentrators, which enhance the performance of solar cells under direct and diffuse illumination. The second part will discuss the design of chiral nanoparticle assemblies that exhibit tunable circular dichroism and may be used as nanoscale biological sensors.

14:20 Invited talk : Nanocavity enhanced light-matter interaction within thin-films and ultra-thin films

Qiaoqiang Gan

University at Buffalo (USA)

While there is great interest in achieving highly absorptive materials exhibiting large broadband absorption using optically thick, micro-structured materials, it is still challenging to realize ultra-compact subwavelength absorber for on-chip optical/thermal energy applications. In this presentation, we will discuss nanocavity enhanced light-matter interaction in thin-films and ultra-thin films with engineered and freely tunable absorption band. These on-chip absorbers can easily be integrated with other on-chip electronic/optoelectronic devices, which is promising to create new regimes of optical/thermal physics and applications.

14:40 Invited talk : 2D materials within long-range hybrid plasmonic modes in asymmetric structures

Charles Lin, Yiwen Su, Wen Ma, Amr Helmy

University of Toronto (Canada)

A novel approach that enables long range hybrid plasmonic modes to be supported in asymmetric structures will be discussed. The utility of these waveguide designs is demonstrated when combined with 2D materials to realize optoelectronic components such as filters, modulators and switches with record footprint, performance and insertion losses.

James Pond, Jens Niegemann, Adam Reid, Roberto Armenta

Lumerical Solutions, Inc. (Canada)

We present an overview of the main challenges when simulating metal and graphene based plasmonic devices combined with other materials such as organics and semiconductors. We review the different numerical methods and demonstrate how they can be used to efficiently design and optimize plasmonic devices. Examples include gap SPR waveguides coupled to nanoantennas, graphene-based silicon modulators, and plasmonic enhanced solar cells.

15:40 : Semi-analytical Design Methodology for Large Scale Plasmonic Networks

M. Swillam (1),Amr Helmy (2)

(1)The American University in Cairo (Egypt) , (2)University of Toronto (Canada)

A semi-analytical approach for efficient modelling of large scale networks of plasmonic slot waveguides is proposed, demonstrated and evaluated. A simple impedance-based model for the junctions is utilized. This efficient and accurate model enables full analysis of a large scale network of without the need for any full wave electromagnetic analysis. The approach is computationally efficient and enables fast design and optimization cycles using these networks
