    Abstract

    mirror plate (100) for a Fabry-Perot interferometer (300) includes
    a substrate (50), which includes silicon (Si),
    a semi-transparent reflective coating (110) implemented on the substrate (50),
    a de-coupling structure (DC1) formed on the substrate (50),
    a first sensor electrode (G1a) formed on top of the de-coupling structure (DC1), and
    a second sensor electrode (G1b),
    wherein the de-coupling structure (DC1) includes an electrically insulating layer (60a), and a first stabilizing electrode (G0a), which is located between the first sensor electrode (G1a) and the substrate (50).
