Nanophotonic devices based on graphene and carbon nanotubes

Abstract

The research presented in the thesis includes the modelling and characterization of the novel devices based on graphene and carbon nanotube (CNT)-based buckypaper. The devices have great potential to be used in applications such as photovoltaics, optical communications/imaging and sensors for oil and gas industry. Graphene is a promising material with excellent optical and electrical properties. Research was carried out in utilizing graphene for photonic and plasmonic devices, including ultra-thin flat lens, plasmonic lens, and oil sensor. Buckypaper extends the applications of CNTs’ excellent properties from nanoscale to microscale. This opportunity was explored in the development of ultra-thin flat lens
