| Abstract | We demonstrate experimentally negative refraction by a photonic crystal prism and imaging of a point source by a photonic crystal slab at 1.5 microm wavelength. The photonic crystal structures were nanofabricated in a InGaAsP/InP heterostructure platform, and optical characterization was performed using a near-field scanning optical microscope. By designing a suitable lens surface termination, an image spot size of 0.12lambda2 was achieved, demonstrating superlens imaging with subwavelength resolution well below Abbe's diffraction limit (0.5lambda2). |
