Résumé

A biosensor device including a metal layer, a transparent substrate layer, and a dielectric layer, wherein the metal layer includes a plurality of sub-wavelength apertures, and wherein the dielectric layer is located between the metal layer and the transparent substrate layer to form a spectrally isolated and well-defined optical transmission resonance through the extraordinary optical transmission (EOT) phenomenon.

Miroir de Bragg

Le miroir de Bragg, mis au point par William Lawrence Bragg (lauréat du prix Nobel de physique de 1915), est une succession de surfaces planes transparentes d’indices de réfraction différents. Il permet de réfléchir, grâce à des phénomènes d’interférences constructives, la quasi-totalité de l’énergie incidente à une longueur d'onde donnée. Ceci est possible à condition que l’onde incidente soit proche de l’incidence normale. Aucun autre miroir ne peut égaler ce résultat (les pertes diélectriques étant plus faibles que les pertes métalliques pour les longueurs d’onde optiques).

Transparent conducting film

Transparent conducting films (TCFs) are thin films of optically transparent and electrically conductive material. They are an important component in a number of electronic devices including liquid-crystal displays, OLEDs, touchscreens and photovoltaics. While indium tin oxide (ITO) is the most widely used, alternatives include wider-spectrum transparent conductive oxides (TCOs), conductive polymers, metal grids and random metallic networks, carbon nanotubes (CNT), graphene, nanowire meshes and ultra thin metal films.

Optical coating

An optical coating is one or more thin layers of material deposited on an optical component such as a lens, prism or mirror, which alters the way in which the optic reflects and transmits light. These coatings have become a key technology in the field of optics. One type of optical coating is an anti-reflective coating, which reduces unwanted reflections from surfaces, and is commonly used on spectacle and camera lenses. Another type is the high-reflector coating, which can be used to produce mirrors that reflect greater than 99.
