Abstract:	Some photonic crystals (PCs) consisting of complex lattices of dielectric cylinders can have an effective refraction index (neff $n_{eff}$ ) of −1. Subwavelength imaging by a slab of a honeycomb PC of dielectric cylinders with neff=−1 $n_{eff} = - 1$ 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.
