Proposed architecture of Burst Photonic Networks is possible to resolve the granularity issue on WDM (Wavelength Division Multiplexing) wavelength path networks. The fundamental structure consists of two tiers of networks, which are a regional network and a long distance network. The regional network is a ring network whose edge nodes are based on optical burst processing, and the long distance networks are based on a WDM wavelength path. At the edge nodes, packets toward the same destination are aggregated into high-speed optical burst data and switched into a particular wavelength path connecting between regional networks through a long distance network.

The SWDM (Super-multi Wave- length Division Multiplexing) with more than 1,000 wavelength has a lot of possibilities for future broadband Internet. The optical source using a Raman Super Continuum and a wide- range wavelength conversion are key techniques to realize the photonic networks based on the SWDM.
