Experimental Investigation of Rapid Wavelength-Switching (<80 ns) in Fast Tuneable Lasers for Applications in Optical Packet and Burst-Switched Networks

چکیده
We report novel results on the improvement in wavelength stability to less than 1-GHz and sub-80ns wavelength tuning times using intelligent wavelength selection in a compact three-section DBR laser module without an active locking mechanism. The performance of the module in terms of switching time and temperature induced wavelength drift is compared to other semiconductor tuneable lasers. The impact of a finite wavelength switching time on the length of datagrams in future optical packet and burst switched networks was investigated by bit error rate (BER) measurements in a WDM experiment. The results are directly applicable to the design of future dynamic optical networks.
