Abstract :
We introduce a paradigm shift in light confinement strategy and show that light can be confined beyond the diffraction limit using transparent artificial media (all-dielectric metamaterials). Our approach controls the optical momentum of evanescent waves - an important electromagnetic property overlooked in photonic devices.
