An example apparatus and optical emission device (200) for preventing the transmission of electromagnetic radiation to and from targeted electrical components of an electronic device are provided. The example apparatus may include an optical emissions component (440, 540, 640, 740, 840, 1140) electrically connected to a target electrical portion (442, 542, 642, 742, 990, 1010, 1142) and configured to generate an optical output (660, 860). The example apparatus may further include a wire bond electromagnetic interference cage (400, 500, 600, 700, 800, 900, 1000, 1100a, 1100b) configured to block the passage of electromagnetic emissions. The wire bond electromagnetic interference cage may include a plurality of bond wires (430, 530, 630, 730a, 730b, 830, 930, 1030, 1130), wherein each bond wire is electrically coupled to an electrical ground (432, 532, 632, 732, 932, 1032, 1132), and wherein the wire bond electromagnetic interference cage overlays at least a portion of the target electrical portion. In addition, the wire bond electromagnetic interference cage may further define an electromagnetic interference cage opening (550, 650, 750, 850) through which the optical output passes.
