PLASMONICS AND OPTOMECHANICS
This research line is mainly focused on the design and characterization of advanced micro- and nano-photonic devices based on plasmonic nanostructures and other complex electromagnetic structures. Plasmonic nanostructures are made of metals, and thus they allow for overcoming the diffraction limit and achieving light manipulation at subwavelength scales. Our final goal is to implement plasmonic micro- and nano-structures on silicon photonics circuits, therefore making use of the fabrication facilities available at NTC.
But not only plasmonic nanostructures can improve the performance of current state-of-the-art silicon photonic chips. Recently, optomechanics has revealed itself as a research hot-topic since it provides adequate mechanisms to make light and sound interact at the nanoscale. In our group, we deal with optomechanical cavities built on silicon chips to manipulate GHz vibrations optically with the final aim of getting ultra-compact microwave photonic circuitry on silicon.
The new research line in the process of consolidation is the development of graphene on non-catalytic substrates for hybrid silicon-graphene photonics. A key challenge to address is to develop wafer scale growth, transfer and nanofabrication protocols providing high mobility devices (over 5,000 cm2V-1s-1) with device-to-device reproducibility and high throughput. We are developing a flow for the integration of monocrystalline graphene in photonics circuits, either by a growth-transfer or by a direct-growth approach. We are focused on the growth of graphene on technologically relevant substrates, mainly sapphire, silicon-on-insulator (SOI), and germanium.
We are convinced that the integration of plasmonic and optomechanical components as well as graphene onto silicon-photonics chips is a key step towards future nanophotonic chips, which is a goal pursued in our research line. Envisaged applications include all-optical signal processing, microwave photonics, nanospectroscopy, and chemo-bio-sensing.
