摘要： A Faraday cage enclosing an optical device extends between a metalized plate and an upper enclosure. The upper enclosure is vertically spaced from the metalized plate. The Faraday cage includes one or more ceramic wall portions that extend from the metalized plate to the upper enclosure and limit the passage of EMI through the ceramic wall portions. The ceramic wall portions include a plurality of laminated ceramic layers, each one of the laminated ceramic layers extending substantially parallel to the metalized plate, and a plurality of vias extending substantially perpendicular to the metalized plate through the laminated ceramic layers, each one of the plurality of vias extending substantially from the metalized plate to the upper enclosure. The plurality of vias are configured to form a pattern that limits the passage of EMI through the vias, wherein the metalized plate, the upper enclosure, and the ceramic wall portions define a Faraday cage that surrounds the optical device.
