A packaged waveguide for passive connectivity includes waveguides packaged in
a
ferrule. The ferrule allows the waveguides to be passively aligned to other waveguides,
fibers, or optical components, such as to align a first waveguide in the ferrule
with a laser diode in a BiDi. In the exemplary embodiment, a second waveguide in
the ferrule the BiDi is at a known and fixed distance apart from the first waveguide
at an end face of the ferrule. A detector in the BiDi may be positioned so that
when the first waveguide is aligned with the laser diode, the second waveguide
is also aligned with the detector. Additional functions can be provided with the
waveguide. The manufacturing of the BiDi with the waveguides packaged in the ferrule
is cost efficient to manufacturer since alignment and connectivity is achieved
passively. The cost efficiency can be further improved by using standard components.
