Tuning pair interactions in colloidal systems using random light fields
Augustin Muster, Diego Romero Abujetas, Frank Scheffold +1
We propose a method to tune interactions between absorptionless colloidal particle pairs. This is achieved via optimization of the spectral energy density of a homogeneous random o…
Long-range quantum emitter interactions mediated by a non-local metasurface: Application to qubit-qubit entanglement
Hannah Riley, Emmanuel Lassalle, Diego Romero Abujetas +3
Scalable quantum technologies demand long-range interactions between many distant quantum emitters (QEs). We introduce non-local metasurfaces supporting bound-states-in-the-continu…
Room Temperature Exciton-Polariton Condensation in Silicon Metasurfaces Emerging from Bound States in the Continuum
Anton Matthijs Berghuis, Gabriel W. Castellanos, Shunsuke Murai +6
We show the first experimental demonstration of room-temperature exciton-polariton (EP) condensation from a bound state in the continuum (BIC). This demonstration is achieved by st…
Optical mirages from spinless beams
Jorge Olmos-Trigo, Diego R. Abujetas, Cristina Sanz-Fernández +2
Spin-orbit interactions of light are ubiquitous in multiple branches of nanophotonics, including optical wave localization. In that framework, it is widely accepted that circularly…
Engineering bound states in the continuum at telecom wavelengths with non-Bravais lattices
