摘要

Some photonic crystals (PCs) consisting of complex lattices of dielectric cylinders can have an effective refraction index (n(eff)) of -1. Sub-wavelength imaging by a slab of a honeycomb PC of dielectric cylinders with n(eff) = -1 is investigated and an open resonator with a quality factor higher than 3000 is designed with the same PC. Air-PC interfaces with low reflection are also used for the slab lens and open resonator.
