Abstract

We extend the analytical entropy model of LiNbO3-based optical Physical Unclonable Functions (PUFs) in two directions. First, we introduce and compare two independent photorefractive suppression pathways: MgO doping (calibrated, four experimental points, zero residual error) and ZnO doping (new, partially calibrated via a real nonlinearity point at 4.6 mol.% ZnO). A critical
