80 Gb/s optimised pulse source using a gain-switched laser diode in conjunction with a nonlinearly chirped grating.
In: ICTON 2005 - 7th International Conference on Transparent Optical Networks, 3-7 July 2005.
The authors demonstrate the generation of transforms limited short optical pulses, which display excellent spectral and temporal qualities by employing a novel technology, based on an externally injected gain-switched laser in conjunction with a non-linearly chirped grating. Using this technique, 3.5 ps optical pulses, exhibiting a time bandwidth product of 0.45, are generated, which are suitable for use in high-speed 80 Gb/s OTDM communications systems.
