Optical Burst Switching (OBS) has been proposed to realize the next generation Internet on the Wavelength Division Multiplexing (WDM) network technology. Optical Burst Switching is an ultra high speed switching technology for optical fiber networks but has the data burst contention problem. In this paper, we introduce Virtual Path (VP) concept addressing burst contention resolutions in OBS networks...
We demonstrate an all-optical wavelength-routing switch monolithically integrated with four wavelength converters and an 8times8 arrayed-waveguide-grating (AWG) filter. In the switch, double-ring-resonator-coupled tunable laser diodes allow rapid and stable switching between output ports (~5 ns) and optical gates based on a parallel amplifier structure prevent the input optical signal from being routed...
A novel integrated filtered feedback tunable laser consisting of a Fabry-Perot laser and integrated filtered feedback section is proposed and demonstrated. The device exhibited a 24-nm tuning range and 1-GHz thermal frequency drift.
A filter-free widely tunable wavelength converter was developed by monolithically integrating a tunable laser based on a double-ring resonator and an optical gate based on a parallel amplifier structure. Wavelength conversion for a 10-Gbit/s NRZ signal is also demonstrated, tunable over a 40-nm range.
