Anomalous reflection coefficient underlying experimentally validated outstanding transmission through metal–dielectric–metal microcavities
Analytical modelling of light transmission through a metal-insulator-metal geometry embedded in a coupling glass surrounding medium is possible through an extended Fabry-Pérot formula. Two distinct coupled surface plasmon resonance branches are allowed inside such microcavity, where two thin…

Lensless hypercentric imaging using digital holography
Hypercentric imaging is a powerful imaging modality that allows for the inspection of a specimen and its sides in the same recording. Typically, hypercentric imaging involves special lens objectives, which are bulky and limit the use of interferometric methods. To overcome this, we introduce…

Structural colour and photonic mechanisms in the blow flies Calliphora vicina and Lucilia richardsi (Diptera: Calliphoridae)
Structural colours in natural organisms are created by complex photonic architectures giving rise to remarkable visual appearances. In arthropods, these structures are usually made of biopolymers and comprise photonic crystals. They are often iridescent, i.e., their colours depend on the incidence…

Polarization camera based fringe locking system for scanning beam interference lithography
A fringe displacement during the exposure process in scanning beam interference lithography (SBIL) systems leads to wavefront errors in linear gratings. The exact orientation of the fringe pattern along the scan direction is also essential for the production of high-quality gratings. In this paper…
