Apparatus and methods for packaging optical communication devices include
optical bench structures, such as silicon-optical benches (SiOB). An
optical communications apparatus includes an optical bench comprising a
substrate having an electrical turning via formed therein. An
optoelectronic (OE) chip and integrated circuit (IC) chip are mounted on
the optical bench and electrically connected using the electrical turning
via. The electrical turning via extends in directions both perpendicular
and transverse to a surface of the substrate such that the OE chip and IC
chip can be mounted on perpendicular surfaces of the optical bench in
close proximity and electrically connected using the electrical turning
via. More specifically, the OE chip and IC chip are mounted on the
optical bench such that a light-emitting or light-detecting surface of
the OE chip is substantially perpendicular to a surface of the IC chip
having contacts, and such that optical transmission lines that are
mounted parallel to the substrate surface can be directly coupled to the
OE chip.
