LIGHT MANIPULATION AND SENSING BASED ON GEOMETRIC RECONFIGURATION OF NANOSCALE OPTICAL SYSTEMS

Tunable optical metasurfaces for amplitude and phase control of light are provided based on electrochemical tuning of the thickness of a polymer spacer between metal structures. The resulting Fabry-Perot and/or plasmon resonances are thereby made tunable, with a figure of merit that can greatly exce...

Zusammenfassung:	Tunable optical metasurfaces for amplitude and phase control of light are provided based on electrochemical tuning of the thickness of a polymer spacer between metal structures. The resulting Fabry-Perot and/or plasmon resonances are thereby made tunable, with a figure of merit that can greatly exceed the figure of merit for electrochromic tuning. This operating principle can be generali zed to provide optical sensing of various environmental parameters such as humidity, pressure etc. Des métasurfaces optiques accordables pour la commande d'amplitude et de phase de la lumière sont fournies sur la base d'un accord électrochimique de l'épaisseur d'un espaceur polymère entre des structures métalliques. Les résonances de Fabry-Pérot et/ou de plasmon résultantes sont ainsi rendues accordables, avec un facteur de mérite qui peut dépasser considérablement le facteur de mérite pour un accord électrochromique. Ce principe de fonctionnement peut être généralisé pour fournir une détection optique de divers paramètres environnementaux tels que l'humidité, la pression, etc.
