Abstract: A small format optoelectronic package or device includes a non-electrically conductive substrate partially covered by an electrically conductive can. The electrically conductive can has a transparent element affixed to an aperture of the electrically conductive can. The electrically conductive can encloses and hermetically seals an edge emitting optical diode, a reflecting mirror, a monitor diode, and conductors between the electrically conductive can and the non-electrically conductive substrate. The non-electrically conductive substrate has three through-holes formed through a thickness of the non-electrically conductive substrate. The three through-holes are filled with an electrically conductive material so as to form three electrically conductive vias. Additionally, a surface of the non-electrically conductive substrate is organized into three regions. The first and third regions have the electrically conductive plating material applied thereto.
