Title: Alternative approach to all-angle negative refraction in two-dimensional photonic crystals

Abstract

We show that with an appropriate surface modification, a slab of photonic crystal can be made to allow wave transmission within the photonic band gap. Furthermore, negative refraction and all-angle negative refraction (AANR) can be achieved by this surface modification in frequency windows that were not realized before in two-dimensional photonic crystals [C. Luo et al., Phys. Rev. B 65, 201104 (2002)]. This approach to AANR leads to different applications in flat lens imaging. Previous flat lens using photonic crystals requires object-image distance u+v less than or equal to the lens thickness d, u+v{approx}d. Our approach can be used to design a flat lens with u+v={sigma}d with {sigma}>>1, thus being able to image large and/or far away objects. Our results are confirmed by finite-difference time-domain simulations.
