Hybrid Epsilon-Near-Zero Modes of Photonic Gap Antennas
Ashutosh Patri, Kévin G. Cognée, David M. Myers +3
We demonstrate that in photonic gap antennas composed of an epsilon-near-zero (ENZ) layer embedded within a high-index dielectric, hybrid modes emerge from the strong coupling betw…
Photonic Gap Antennas Based on High Index-Contrast Slot-Waveguides
Ashutosh Patri, Kévin G. Cognée, Louis Haeberlé +3
Optical antennas made of low-loss dielectrics have several advantages over plasmonic antennas, including high radiative quantum efficiency, negligible heating and excellent photost…
Organic Photodiodes with an Extended Responsivity using Ultrastrong Light-Matter Coupling
Elad Eizner, Julien Brodeur, Fábio Barachati +2
In organic photodiodes (OPDs) light is absorbed by excitons, which dissociate to generate photocurrent. Here, we demonstrate a novel type of OPD in which light is absorbed by polar…
Generation of Rabi frequency radiation using exciton-polaritons
Fábio Barachati, Simone De Liberato, Stéphane Kéna-Cohen
We study the use of exciton-polaritons in semiconductor microcavities to generate radiation spanning the infrared to terahertz regions of the spectrum by exploiting transitions bet…
Optical and Structural Properties of Ultra-thin Gold Films
Anna Kossoy, Virginia Merk, Denis Simakov +3
Realizing laterally continuous ultra-thin gold films on transparent substrates is a challenge of significant technological importance. In the present work, formation of ultra-thin…
Strong light-matter coupling in two-dimensional atomic crystals
Xiaoze Liu, Tal Galfsky, Zheng Sun +5
Two dimensional (2D) atomic crystals of graphene, and transition metal dichalcogenides have emerged as a class of materials that show strong light-matter interaction. This interact…
