000000863 520__ $$aIn this thesis we present the study of the implementation of ultrashort pulses using frequency comb generation in a Mach-Zehnder modulator and chirp compensation in a standard single-mode fiber. Two possible configurations have been developed and optimized to obtain a picosecond pulse train. An additional stage of pulse compression was necessary to arrive to femtosecond pulses, and a nonlinear fiber was employed. An analysis of a complete optical communication system using the generated pulses with OOK modulation and OTDM was devoted and a relation between pulse parameters and the BER sensitivity was evaluated. A numerical model with Matlab software has been developed for the required analysis. Finally, an experimental solution of the pulse source has been devoted in the Fotonik’s laboratory, obtaining results that we compared with the simulated ones.
