Our main scientific interest is nanophotonics and in particular the coherent interaction of light with mesoscopic and nanoscale photonic systems, individually and collectively. It involves a combination of nano-optics, quantum optics and photonics of complex systems.
We explore quantum and nanoscale photonics to control the generation, confinement and flow of light. We look at coherent interactions of light emitted from a single quantum dot or a molecule with nanoscale engineered materials, such as nanometer-sized optical resonators and metallic antennas, at the individual level, which are also the building blocks for more complex optical networks.
We are interested in understanding how quantum information can travel long distances by coupling photons and emitters via tailored optical modes of complex optical networks. We expect fascinating collective phenomena to emerge from these complex architectures, and by inducing stimulated emission we will explore unconventional and random lasing.

Complex Photonic Networks
Applications are invited from EU nationals for a fully funded PhD studentship in experimental nanophotonics at King’s College London. You will study the coherent interaction of light with nanoscale photonic systems; a combination of nano-optics, quantum optics and photonics of complex systems. The challenge is to achieve ultimate control of light emission from individual emitters to realize complex photonic networks exploiting quantum and coherent effects. The project builds on the latest advances in nanophotonics, plasmonics and photonic crystal science, which gives powerful tools to control light-matter interaction at the nanoscale. We are seeking an enthusiastic PhD student to undertake experimental research. The project involves design, nanofabrication and optical studies. The successful candidate should have a degree in physics, or material science. Independent thinking and multidisciplinary attitude is sought. For further details contact Dr Riccardo Sapienza.
Unconventional and random lasing
You will study stimulated emission of light and lasing in nanoscale photonic systems such as complex networks and porous media. The challenge is to achieve novel forms of lasing, based on novel optical modes, driven by near-field interactions, multiple light scattering and collective interference in optical networks. The project builds on latest advances in nanophotonics and plasmonics, tools to control light-matter interaction at the nanoscale. For further details contact Dr Riccardo Sapienza.
