Abstract

Negative ray refraction in optimized nonuniform triangular 2D photonic crystal slabs is used for efficient far-field refocusing of a point source. It is shown by numerical simulations that photonic crystal slabs with thicknesses between 10 and $0.6\mathrm{\mu }\mathrm{m}$ in conjunction with proposed superstructure transitions are able to refocus a point source diffraction limited with efficiencies of up to 97%.
