Enhancement of Circular Dichroism in Chiral Dielectric Metasurfaces by Ion Beam Irradiation
Advanced Optical Materials, EarlyView.Ion beam irradiation enables post fabrication tuning of dissipative losses in chiral dielectric metasurfaces composed of C4 symmetric silicon nanostructures. By tailoring the absorption toward critical coupling condition, circular dichroism is enhanced from 0.70 to 0.85, demonstrating a versatile route for maximizing optical chirality and polarization ...
