Abstract:
An optoelectronic package comprising:a non-electrically conductive substrate having a first surface and a second surface, the first surface separated from the second surface by a thickness of the non-electrically conductive substrate, the first surface having a first region, a second region, and a third region, the first region having a first through-hole extending through the thickness, the second region having a second through-hole extending through the thickness and a third through-hole extending through the thickness, the first region being separated from the third region by the second region;an electrically conductive plating substantially covering both the first region and the third region of the first surface;an electrically conductive material substantially filling the first through-hole so as to form a first electrically conductive via, the electrically conductive material substantially filling the second through-hole so as to form a second electrically conductive via, and the electrically conductive material substantially filling the third through-hole so as to form a third electrically conductive via, and the electrically conductive planing substantially covering the first region being electrically connected to the electrically conductive material substantially filling the first through-hole;an optical diode having a first lead and a second lead, the first lead of the optical diode electrically connected to the electrically conductive plating of the first region, the first lead of the optical diode electrically connected to the first electrically conductive via, the second lead of the optical diode electrically connected to the second electrically conductive via, the optical diode having an optical axis;a monitor diode having a third lead and a fourth lead, the third lead of the monitor diode electrically connected to the electrically conductive plating of the first region, the third lead of the monitor diode electrically connected to the first electrically conductive via, the fourth lead of the monitor diode electrically connected to the third electrically conductive via;an electrically conductive can having a first aperture and a second aperture; anda transparent element mounted on and sealed to the first aperture of the electrically conductive can, and whereinthe second aperture of the electrically conductive can is mounted on and sealed to the electrically conductive plating adhered to the third region of the non-electrically conductive substrate so as to hermetically seal the monitor diode and the optical diode from an ambient atmosphere, and whereinthe first through-hole has a longitudinal axis, and wherein the longitudinal axis of the first through-hole passes through at least one of the optical diode and the monitor diode, and whereinthe optical axis of the optical diode passes through the transparent element, and wherebya conductive substrate and posts are absent so as to reduce a size of the optoelectronic package.
