1. A sensor unit, comprising:

  • a sensor element having a substrate and a plurality of optical components integrated on said substrate;

    said plurality of optical components including at least one integrated measurement waveguide forming an integrated optical sensor for measuring an electric variable and at least one further optical component integrated on said substrate and forming a further integrated optical sensor;

    said optical sensors being selected from the group consisting of;

    a) an optical current sensor based on the Faraday effect for measuring an electric current in a current-carrying conductor;

    b) an optical voltage sensor based on the Pockels effect for measuring an electric voltage;

    c) an optical expansion sensor for measuring an expansion; and

    d) a wavelength sensor for measuring a change in an optical wavelength.
