The objectives of
the AAPN research program include:
- Developing network architectures and components that
move the photonic edge, the border of the core where data
flow experiences no optoelectronic conversion, functionally
and geographically closer to the end user.
- Developing agile network reconfiguration techniques to
respond to changing traffic patterns.
- Using both time and wavelength to achieve a higher
degree of data flow granularity; by combining Wavelength
Division Multiplexing (WDM) with optically slotted or
burst-switched Time Division Multiplexing (TDM), we will
parse network traffic into small bandwidth bins of time and
- Performing switching and routing using all-photonic
means, thus increasing the fraction of signal processing
- Managing traffic electronically at the photonic edge by
controlling core switches via dedicated electrical or
optical out-of-band connections.
- Developing an understanding of physical layer
transmission impairments that arise from new traffic
patterns generated in AAPNs.
- Designing dynamic components (amplifiers, regenerators,
polarization compensators) to manage these transmission
- Realizing fast switches capable of supporting the level
of time and wavelength granularity required to achieve
target network performance.
- Designing compact, highly functional modules for
switching and routing.
