Precise intensity and phase characterisation of optical telecommunication signals

In this thesis, the accurate characterisation of a range of high speed optical telecommunication signals is presented. The main technique used to determine both the intensity and the phase profiles of these signals is based on spectrograms, and various developments and extensions of this method are presented. Finally, data modulated pulses in a 40 Gbit/s system are characterised before and after propagation in an installed fibre link, and excellent agreement is found between the information retrieved from the spectrogram method, independent intensity measurements and theoretical expectations.
