A new technique using high-index glasses enables photonic device integration on substrates such as semiconductors, glasses, IR crystals, polymers, and graphene.
Diffractive arrays of metallic nanoparticles act as nanoantenna-phased arrays that enhance emission from thin phosphor layers in defined directions, and therefore offer new prospects for solid-state lighting.
