Abstract:
1. An array optical sub-assembly, comprising: a base seat; a transparent substrate parallel with the base seat to form a space therebetween; an integrated circuit mounted on a surface of the base seat within the space; a photoelectric element mounted on a first side of the transparent substrate within the space and electrically coupled to the integrated circuit, the photoelectric element and the integrated circuit being spaced from each other, such that heat generated by the integrated circuit is not directly transferred to the photoelectric element, and; a microlens array located on a second side of the transparent substrate opposite to the photoelectric element to enhance the optical coupling efficiency of the photoelectric element; wherein the photoelectric element and the transparent substrate are bonded through a silver paste or solder balls; and wherein the base seat has at least one metal conductive wire to serve as a circuit to electrically connect the photoelectric element and the integrated circuit.
