Current research projects are:

  • Quantum Metasurface: A Novel Platform for Generating and Manipulating Single Photons (Villum Young Investigator) project aims to develop a novel quantum metasurface platform for generating and manipulating single photons at room temperature by integrating quantum emitters based on nano-diamonds containing color centers with optical metasurfaces. In-depth investigations of the quantum metasurface platform concentrate on two interrelated and largely unexplored research areas within quantum nanophotonics: efficient on-demand generation of single photons with arbitrary wavefronts and realization of robust on-chip sources of entangled photons.
  • Tuning emission of charged excitons in two-dimensional transition metal dichalcogenide monolayers (Marie S.-Curie Fellowship) project is focusing on exploration of electro-chemical charge doping of transition metal dichalcogenide monolayers for controlling 2D charged excitons with valley degrees of freedom. The controllable exciton charging provides the tunability of emission for further deterministic interfacing with nano photonic antennas towards development of bright and directional valleytronic sources of quantum light.
  • Room-Temperature Generation of Indistinguishable Single Photons (Villum Experiment) project concerns the emission-rate of a special quantum emitter (Group IV color center in a nanodiamond, which interacts less with phonons due to its position in the lattice) that should be enhanced by utilizing a combination of a gap-plasmonic structure with ultra-small gaps (<2nm) and a dielectric cavity. This combination should provide us with the necessary enhancement in emission rate to make it larger than its rate of interaction with phonons at room temperature. In addition to generating indistinguishable photons, it should also make the communication between quantum nodes faster than terabits/s.
  • Towards single-photon nonlinear optics with polaritons in atomically-thin materials (Sapere Aude) project seeks to engineer the extreme optical field confinement associated with two-dimensional polaritons in atomically-thin materials to actuate nonlinear optical phenomena at ultra-low light powers, ultimately reaching a regime where individual light quanta interact strongly and in a deterministic manner.
  • Quantum project is focusing on quantum plasmonics, i.e., the interaction of light with metallic nanostructures in situations where classical electrodynamics is interfacing regimes with quantum physics.

Former research projects:

The ERC grant deals with two largely unexplored research areas within plasmonics:
Development of ultra-compact plasmonic configurations exhibiting unique functionalities and the realization of strong coupling between extremely confined plasmonic modes and individual quantum emitters. Particularly, the project focuses on (i) dynamic control of plasmon-waveguide modes using the same metal circuitry for both radiation guiding and its control with electrical signals; (ii) moulding the radiation flow by gradually varying waveguide cross sections in order to realize efficient nanofocusing of radiation, miniature ultra-dispersive wavelength-selective components and table-top models of plasmonic black holes, and (iii) quantum plasmonics with individual quantum emitters being strongly coupled to deep subwavelength surface plasmon modes.

  • ANAP 

    Active nano-plasmonics, which is devoted to the development of the foundation for ultra-compact nanophotonic components via optical nanotechnology based on SP modes supported by dielectric/metal nanostructures.

  • PhoxTroT 

    Large-scale integrated research project focusing on high-performance, low-energy and cost and small-size optical interconnects (including long-range plasmon waveguides) across the different hierarchy levels in data center and high-performance computing systems: on-board, board-to-board and rack-to-rack.
  • Theoretical studies and experimental investigations of low-dimensional optical metamaterials, i.e., optical metasurfaces, based on the concept of detuned electrical dipoles and nanoresonators involving gap SP modes (supported by the Danish Council for Independent Research, Natural Sciences).

  • PlasTPV 

    Theoretical studies and experimental investigations of innovative configurations based on plasmonic metal nanostructures for thermophotovoltaics, i.e., SP-based components that would be capable of broadband absorption and those for narrowband emission of radiation.
