Imaging properties of large field-of-view quadratic metalenses and their applications to fingerprint detection
Emmanuel Lassalle, Tobias W. W. Mass, Damien Eschimese +5
Dielectric metasurfaces, extremely thin nanostructured dielectric surfaces, hold promise to replace conventional refractive optics, such as lenses, due to their high performance an…
Long-lifetime coherence in a quantum emitter induced by a metasurface
Emmanuel Lassalle, Philippe Lalanne, Syed Aljunid +4
An anisotropic quantum vacuum (AQV) has been predicted to induce quantum interferences during the spontaneous emission process in an atomic -transition [G. S. Agarwal, Phys. Rev…
Interplay between spontaneous decay rates and Lamb shifts in open photonic systems
Emmanuel Lassalle, Nicolas Bonod, Thomas Durt +1
In this letter, we describe the modified decay rate and photonic Lamb (frequency) shift of quantum emitters in terms of the resonant states of a neighboring photonic resonator. Thi…
Lamb shift multipolar analysis
Emmanuel Lassalle, Alexis Devilez, Nicolas Bonod +2
It is now well established that radiative decay of quantum emitters can be strongly modified by their environment. In this paper we present an exact, within the weak-coupling appro…
Conditions for anti-Zeno effect observation in free-space atomic radiative decay
Emmanuel Lassalle, Caroline Champenois, Brian Stout +2
Frequent measurements can modify the decay of an unstable quantum state with respect to the free dynamics given by Fermi's golden rule. In a landmark article, Nature 405, 546 (2000…
