Optical components and associated methods of manufacturing are provided. An example optical component includes a body defined by an optical interposer substrate and a passivation layer applied to the optical interposer substrate. The optical interposer substrate defines a first surface of the body, and the passivation layer defines a second surface of the body opposite the first surface. The passivation layer includes a metallic shielding element configured to prevent interference between the first surface and the second surface. The optical component further includes an opening extending from the second surface to the optical interposer substrate, the opening defining an optical path through the passivation layer. The optical interposer substrate receives an optical signal from an optical transmitter supported by the second surface via the optical path.
