Field-enhancement and nonlocal effects in epsilon-near-zero photonic gap antennas
Félix Thouin, David M. Myers, Ashutosh Patri +4
In recent years, the large electric field enhancement and tight spatial confinement supported by the so-called epsilon near-zero (ENZ) mode has attracted significant attention for…

Compact grating coupler using asymmetric waveguide scatterers
Ashutosh Patri, Xiao Jia, Muhammad Mohsin +2
We demonstrate a novel grating coupler design based on double asymmetric and vertically oriented waveguide scatterers to efficiently couple normally incident light to a fundamental…
