Optical imaging with photonic hyper-crystals: Veselago lens and beyond

We present an optical imaging system based on the recently introduced concept of photonic hyper-crystal, an artificial optical medium combining the properties of hyperbolic materials and photonic crystals. The proposed device functions as a Veselago lens with a nearly constant negative refractive index and substantially reduced image aberrations. The planar nature of this lens offers significant applications in nano-photolithography and hot-spots diagnosis in silicon-based semiconductor devices.
