Demonstration of a Monolithic and Fully Telecom-Fiber-Compatible Tunable Source of Polarization Entangled Photon Pairs Based on a van der Waals Material
Benjamin Laudert, Fatemeh Abtahi, Duk Choi +2
We present a tunable, single-mode-optical-fiber-based source of polarization entangled photon pairs for the near-infrared telecommunication band that is deployable in standard infr…
Stabilizing van der Waals NbOI2 by SiO2 encapsulation for Photonic Applications
Gia Quyet Ngo, Fatemeh Abtahi, Jakub Regner +6
Niobium oxide diiodide (NbOI2) is an emerging material for photonics and electronics, distinguished by its exceptional second-order nonlinearity and pronounced in-plane ferroelectr…
Thickness-dependence of Linear and Nonlinear Optical Properties of Multilayer 3R-MoS2
Fatemeh Abtahi, Alen Shaji, Gia Quyet Ngo +4
3R-MoS2, a MoS2 polytype with broken inversion symmetry, enables unique light-matter interactions and is promising for linear and nonlinear integrated photonics beyond the monolaye…
Structural and Optical Properties of Crystal Ion Sliced BaTiO Thin Films
Hossein Esfandiar, Fatemeh Abtahi, Trevor G. Vrckovnik +10
Barium titanate (BaTiO) is a compelling material for integrated photonics due to its strong electro-optic and second-order nonlinear properties. Crystal Ion Slicing (CIS) prese…
