Here we numerically demonstrated that the phase profile of a given temporal optical pulse can be retrieved by photonic semi-differintegration, where by semi-differintegration we mean either a 0.5th-order differentiation or integration. In both cases, the signal’s temporal phase can be obtained by simple dividing two temporal intensity profiles, namely the intensities of the input and output pulses of a spectrally-shifted semi-differintegral. In both cases, we obtained simple analytical expressions for the phase profile. We numerically prove the viability of these proposals.
