Measurement of autocorrelation and spectrum of optical pulses does neither allow to determine the amplitude and phase of the pulse in the time domain nor even unically determine its intensity. The frequency resolved optical gating (FROG) is usually employed for full characterization of optical pulses. The project is aimed on FROG method based on cross-phase modulation in microstructured optical fiber. This methods allows unique characterization of optical pulses. The microstructured fiber can be designed in such a way that in possesses low dispersion and high nonlinear coefficient not achievable in conventional optical fiber. It is possible to achieve good sensitivity due to the long interaction length so this method is suitable for characterization of optical pulses with energy bellow 10 pJ. We would like to analyze theoretically two measurement set-ups and one of them to realize experimentally. We would like also develop method of data analysis that would allow to characterize solitary pulses as well as periodic pulses.
