Single-Photon Nanoantenna with in Situ Fabrication of Plasmonic Ag Nanoparticle at an hBN Defect Center
Oğuzhan Yücel, Serkan Ateş, Alpan Bek
We present a practical new method for fabricating a coupled single quantum emitter-plasmonic nanoantenna system. Emission characteristics of a single defect center embedded in hexa…
A quantum emitter coated with graphene interacting in the strong coupling regime
Mehmet Günay, Vasilios Karanikolas, Ramazan Sahin +3
We demonstrate the strong coupling of a quantum dot and a graphene spherical shell coating it. Our simulations are the exact solutions of 3D Maxwell equations. Interaction produces…
Plasmon lifetime enhancement in a bright-dark mode coupled system
Bilge Can Yildiz, Alpan Bek, Mehmet Emre Tasgin
Metallic nanoparticles can localize the incident light to hotspots as plasmon oscillations, where the intensity can be increased up to four orders of magnitude. Even though the lif…
Enhanced spontaneous down-conversion in a nonlinear crystal embedded with plasmonic-quantum emitter hybrid structures
Zafer Artvin, Mehmet Emre Tasgin, Alpan Bek +1
Control of nonlinear response of nanostructures via path interference effects, i.e. Fano resonances, has been studied extensively. In such materials, a frequency conversion process…
