TOM 11 Waves in Complex Photonic Media

Long-range propagation of material excitations under strong light-matter coupling

Vinod Menon

City College & Grad Center of CUNY, United States of America

In this talk we will discuss the long-range transport of strongly coupled exciton-polaritons in disordered organic molecular systems and 2D semiconductors. Specifically, we will present our recent work on long-range transport and averaging out of disorder through strong coupling of highly localized Frenkel excitons with propagating Bloch surface waves in organic materials. Following this we will discuss exciton-polariton propagation in 2D transition metal dichalcogenides. In this context, we will discuss our work on routing of valley polarized emission from 2D TMDs through their coupling to Bloch surface modes.

Artificial Intelligent flexible meta-surfaces with 99% experimental efficiency for vectorial light control

Andrea Fratalocchi

KAUST, Saudi Arabia

Integrating conventional optics into compact nanostructured surfaces is the goal of flat optics. Despite the enormous progress in this technology, there are still critical challenges for real-world applications due to the limited operational efficiency in the visible region, on average lower than 60%, which originates from absorption losses in wavelengththick (≈ 500 nm) structures. Another issue is the realization of on-demand optical components for controlling vectorial light at visible frequencies simultaneously in both reflection and transmission and with a predetermined wavefront shape...

Resonance frequency and radiative Q-factor of plasmonic and dielectric modes of small objects

Carlo Forestiere, Giovanni Miano, Rubinacci Guglielmo

University of Naples "Federico II", Italy

The electromagnetic scattering resonances of a non-magnetic object much smaller than the incident wavelength in vacuum can be either described by the electroquasistatic approximation of the Maxwell's equations if its permittivity is negative, or by the magnetoquasistatic approximation if its permittivity is positive and sufficiently high. These two approximations fail to correctly account for the frequency shift and the radiative broadening of the resonances . Here, closed form expressions of the frequency-shift and the radiative Q-factor of both plasmonic and dielectric modes of small objects are introduced.
