چکیده انگلیسی
We present a novel system design that can generate the optimized wavelength-tunable optical pulse streams from an uncooled gain-switched Fabry-Perot semiconductor laser using an optical amplifier as external light source. The timing jitter of gain-switched laser has been reduced from about 3Â ps to 600Â fs and the pulse width has been optimized by using our system. The stability of the system was also experimentally investigated. Our results show that an uncooled gain-switched FP laser system can feasibly produce the stable optical pulse trains with pulse width of 18Â ps at the repetition frequency of 5Â GHz during 7Â h continuous working. We respectively proved the system feasibility under 1Â GHz, 2.5Â GHz and 5Â GHz operation.
