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…
Spontaneous emission dynamics of ions coupled to hyperbolic metamaterials
Gabriel I. López-Morales, Mingxing Li, Ravindra K. Yadav +4
Sub-wavelength nanostructured systems with tunable electromagnetic properties, such as hyperbolic metamaterials (HMMs), provide a useful platform to tailor spontaneous emission pro…
