Abstract: 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.

Abstract: An optical bench includes a substrate having a fiber receiving area, a lens mounting area, and a reflective area. The fiber receiving area, the lens mounting area and the reflective area are positioned linearly. The fiber receiving area includes a V-groove etched or micromachined in the substrate, wherein a length of optical fiber cable is inserted in the V-groove to facilitate alignment of optical fiber cable towards the lens mounting area. The lens mounting area includes first support members for supporting a lens positioned to facilitate directing of light from the optical fiber cable towards the reflective area. The reflective area includes a planar mirror and second support members, wherein the second support members support a diode positioned above the planar mirror, wherein the planar mirror is positioned in a slanted angle to facilitate directing of light from the lens to the diode.
