| Abstract: | The various technologies presented herein relate to integrating an IC
having at least one waveguide incorporated therein with a v-groove array
IC such that an optical fiber located in a v-groove is aligned relative
to a waveguide in the IC maximizing optical coupling between the fiber
and the waveguide. The waveguide IC and the v-groove array IC are bonded
in a stacked configuration. Alignment of the waveguide IC and the array
IC in the stacked configuration enables advantage to be taken of
lithographic accuracy of features formed with respect to the Z-direction.
Further, kinematic pins and sockets are utilized to provision accuracy in
the X- and Z-directions, wherein advantage is taken of the placement
accuracy and fabrication tolerance(s) which can be utilized when forming
the and sockets. Accordingly, automated alignment of the waveguide IC and
the array IC is enabled, facilitating accurate alignment of the
respective waveguides and fibers. |
