Abstract

The construction of the multifocal Veselago lens predicted earlier [Appl. Opt. 42, 5701 (2003)] is proposed on the basis of a uniaxial photonic crystal consisting of cylindrical air holes in silicon that make a triangular lattice in a plane perpendicular to the axis of the crystal. The object and images are in air. The period of the crystal should be 0.44μm to work at the wavelength 1.5μm. The lens does not provide superlensing, but the halfwidth of the image is 0.5λ. The lens is shown to have wave-guiding properties, depending on the substrate material.
