Abstract:
1. An optical transmission device comprising: a support block having a supporting surface and a mounting surface, the mounting surface having a plurality of contact pads, and the supporting surface having a cathode pad and an anode pad; a groove formed on the supporting surface, the groove encircling the cathode and anode pads; an elastic o-ring that is set within the groove; electrical traces that connect the cathode and anode pads with respective contact pads; a first photonic device attached to the cathode pad and connected to the anode pad; a receptacle that is attached to the supporting surface, the receptacle having a protruding rim that conforms to the outline of the groove, the rim being inserted into the groove whereby the o-ring is compressed, the receptacle also having a first receptacle opening and at least one stem that is in contact with the support surface, the stem acting to maintain a standoff separation distance between a first glass lens and the first photonic device; and the first glass lens attached within the first receptacle opening such that the first glass lens is positioned above the first photonic device, wherein the first photonic device is sealed between the receptacle, the first glass lens, and the supporting surface.
