Abstract

We demonstrated the clear light focusing in a photonic crystal superlens. We fabricated it on SOI substarate with optimum interfaces for suppressing reflection and diffraction losses. We observed near field patterns of light propagation in the superlens, which showed the light focusing in a wide frequency range inside and outside of the light cone. We also confirmed that the focal length, NA, and the spot width, which ageed well with theory. The smallest spot width was 1.8 μm at ω= 1.39 μm. In addition, we demonstrated the real image formation using multiple light sources.
