    Extraction of individual Pockels coefficients of thin films via interferometric reflection measurements by Kobe De Geest, Enes Lievens, Ewout Picavet, Klaartje De Buysser, Dries Van Thourhout, Jeroen Beeckman

    Published 2025-01-01
    “…Ferroelectric thin films integrated on passive photonic platforms offer ways to achieve functionalities that are otherwise impossible or inefficient, such as electro-optic (EO) modulation, acousto-optic modulation or optical nonlinear conversion. Characterization methods of the EO properties of thin films are often only able to extract an effective EO response, while in many integrated photonic circuits it is one of the Pockels coefficients that determines the strength of the modulation. …”
