Pupil replication with crossed gratings in an AR display is modelled and characterised. It is found that, compared to linear gratings, crossed gratings in a hexagonal lattice offer an additional degree of freedom to control the angular spread of pupi

We address numerically two important aspects of HAMR (heat-assisted magnetic recording) near-field transducer (NFT) design, namely media-impedance matching and hot spot thermal curvature flattening. A scheme to tune the NFT-media impedance mismatch r

Graphene possesses innate potential to replace indium tin oxide (ITO) as the transparent electrode in an organic solar cell device. From our transmittance study weighted with the air mass 1.5 global (AM1.5G) solar spectrum, it is found that a higher

Heat-assisted magnetic recording (HAMR) is a potential enabling technology for ultrahigh density data storage systems. In HAMR, a near-field transducer (NFT) delivers a subdiffraction heat spot to record bits of data on a high-anisotropy magnetic med

Simulations are presented that demonstrate that the global state of spatial coherence of an optical wavefield can be altered on transmission through an array of subwavelength-sized holes in a metal plate that supports surface plasmons. It is found th

It has been demonstrated recently that surface plasmons can change the state of coherence of light emanating from a Young’s double-slit interferometer. This suggests the possibility of developing a “coherence-converting” device with a large arr

A condition for the complete destructive interference of partially coherent fields emerging from pinholes in an opaque screen is derived, with the assumption of symmetry in both their geometric positions and coherence properties. We use this conditio

We present a beam focusing flat lens for use in the mid-infrared wavelength range. The layer structure used is a 360 nm thick amorphous silicon layer on 200 nm thick aluminium on a 300 µm thick Borosilicate Glass Substrate. An aperture through the A
