Abstract

A simple superlens formed by a one-dimensional dielectric photonic crystal is introduced. Off-axis subwavelength focusing is achieved and studied with the equifrequency contour analysis and finite-difference time-domain simulation. Besides its advantage of simplicity, the present superlens can give a spot size much smaller than that achieved by a slab of some high-dimensional photonic crystal of negative refraction. The properties of an on-axis image achieved by the combination of two slabs of the one-dimensional photonic crystal are also studied.
