In-fiber second-harmonic generation with embedded two-dimensional materials
Gia Quyet Ngo, Emad Najafidehaghani, Ziyang Gan +10
Silica-based optical fibers are a workhorse of nonlinear optics. They have been used to demonstrate nonlinear phenomena such as solitons and self-phase modulation. Since the introd…
Scalable functionalization of optical fibers using atomically thin semiconductors
Gia Quyet Ngo, Antony George, Robin Tristan Klaus Schock +14
Atomically thin transition metal dichalcogenides are highly promising for integrated optoelectronic and photonic systems due to their exciton-driven linear and nonlinear interactio…
Tuning the Effective PT-Phase of Plasmonic Eigenmodes
Alessandro Tuniz, Torsten Wieduwilt, Markus A. Schmidt
We experimentally observe an effective PT-phase transition through the exceptional point in a hybrid plasmonic-dielectric waveguide system. Transmission experiments reveal fundamen…
