Arrayed wave guide devices are the
foundations of the next generation optical fiber communication technology development,
which have bright and wide application prospects. These arrayed waveguide
chips, similar in many ways to their electronic counterparts, are fabricated
using wafer-level processing techniques and use optical waveguides to route
photons, the same way that metal traces are used toroute electrons in an
electronic chip. These devices include optical beam splitters/combiners for
branching/ combining optical signals, optical switchers for changing optical
paths, optical filtering for introducing multiple optical channels into a
single optical fiber, and so on. These devices have many features, such
ascompact structure, strong noise immunity, excellent property, and easy
automation production, which are the developing frontiers of optoelectronic
devices at present. Arrayed waveguide devices are rich in theirs categories and
structures. With the rapid increasing demands for the quality devices of
optical fiber communication system, many problems about mechanisms and rules of
manufacturing process for arrayed waveguide devices packaging must be
investigated more profoundly, in order to make a breakthrough in the
manufacturing technologies, processes and equipment of arrayed wave guide
devices.
