Dr Riccardo Sapienza is a Lecturer in Physics at King’s College London and received his Master in Physics in 2001 from the University of Padova in Italy. He holds a PhD from LENS, The European Laboratory for Non-Linear Spectroscopy and before joining King’s he worked at the ICMM Instituto de Ciencia de Materiales de Madrid, the Langevin Institute in Paris and the ICFO The institute of Photonic Sciences in Barcelona.
Riccardo’s 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.
He explores quantum and nanoscale photonics to control the generation, confinement and flow of light. He 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.
Riccardo and his team are interested in understanding how quantum information can travel long distances by coupling photons and emitters via tailored optical modes of complex optical networks. They 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 towards nanoscale quantum optics.
We are seeking an enthusia 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 achievecomplex 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.
The project combines network theory with nanophotonics, with the goal of studying how single emitters can be controlled and boosted in nanophotonic networks, towards quantum optics at the nanoscale.
Applicants must hold, or expect to receive, a first or upper second class honours degree (or equivalent) in Physics, Material Science or related disciplines. Independent thinking and multidisciplinary attitude is sought.
Based in the Experimental Biophysics and Nanotechnology Group of the Department of Physics at King’s College London, in the team of Dr Riccardo Sapienza (sapienzalab.org) we are very well placed to offer a stimulating environment for this project. We have excellent, state-of-the-art lab facilities and all the necessary equipment. Furthermore, the College offers a huge range of seminars and transferrable-skills courses that can provide a competitive edge in today’s job market.
The starting-date can be anytime.
Please submit a CV to firstname.lastname@example.org.
The project as such is available to all students, regardless of nationality. However, full funding (tax-free stipend + tuition fees) can only be offered to students who meet the EPSRC eligibility criteria (UK/EU students who have been resident in the UK for 3 years prior to starting their PhD-programme; see here: https://www.epsrc.ac.uk/skills/students/help/eligibility/). In addition, the stipend can be topped-up as we always require teaching-assistants for various lectures or undergraduate labs where appropriate.
