Superlens, hyperlens or, more completely, super-resolution lenses are devices which are able to image beyond the diffraction limit in both near- and far-field.
These materials, called negative index materials, offer the promise of devices with unique capabilities; for example, super resolution lenses and optical cloaks.
In this paper, instead of the usage of the larger size aperture lens and super-resolution technology in the free-space laser communication system, we introduce photon sieve to compress the center spot in the diffractive far field, which can decrease the weight of the emitting lens.
The left-handed lens achieves super-resolution by resurrecting waves that carry the subwavelength details of an object.
In some cases where poor video quality is due to hardware limitations, namely the complementary metal-oxide semiconductor (CMOS) sensor resolution or a lens on a camera, super-resolution can be used to help rectify or improve video quality.
There are considerable engineering applications for the nanoring-based superfocusing lenses, ranging from the super-resolution imaging, particle acceleration, quantum optical information processing to the optical data storage.
Applications of surface plasmon polaritons 1 (SPP) have been extensively developed in the field of optoelectronics, such as plasmonic circuitry (e.g., waveguides, interferometric logic, and modulators), 2 nanolasers, 3 ultrahigh-efficiency sensors, 4 photovoltaics, 5 super-resolution imaging, 6 and various two-dimensional plasmonic lens.
Over the past few decades, metamaterials with various designs and structures have been investigated for super-resolution imaging field to offer many different types of lenses which can overcome diffraction limit.
We outlined a method to modify the surfaces of aspheric lenses and mirrors in order to achieve super-resolution.
