Metamaterials
Objectives
This line is focused on the design of devices based on photonic metamaterials.
Metamaterials are usually made of nano-structured metals exhibiting plasmonic resonances at optical frequencies. These resonances are responsible for unusual electromagnetic phenomena such as negative refraction, sublambda imaging, and extraordinary transmission.
We are working on the connection between the extraordinary transmission phenomena and negative index origin in certain structures.
Work is also progressing on the design of structures based on photonic crystals in order to produce the above phenomena.
To analyse the devices designed in this area and built in the Nanofabrication line, we have access to a BRUKER FTIR spectrometer. This enables us to obtain the response of these devices over a wide spectral region – ranging from middle infrared to ultraviolet.
