The article forecasts structured optical metamaterials as basis for a superlens that can image at beyond the diffraction limit and that can operate in the optical regime and are practical to fabricate into a superlens. The researchers at Princeton University in New Jersey are developing the concept that can be either be applied to imaging in one dimension, similar to a cylindrical lens or imaging in two dimensions like a spherical lens.

Focuses on a solid-optics component, termed an X-cube developed by researchers at the NEC Research Institute in Princeton, New Jersey. Functions of the solid-optics component; Description of the X-cube.

Provides information on a study by the NEC Research Institute in Princeton, New Jersey that combined free-space optics with guided-wave optics to produce a hybrid circuit that has the advantages of both. Names of the researchers which developed the optics; Overview of the process of combining the optics; Limitation of the circuit system.
