In particular, all-optical time differentiation, time integration and true time reversal are theoretically predicted, and then numerically and experimentally demonstrated. The technique can be exploited to process both photonic and ultra-wide band microwave signals, so enabling many applications in photonics and in radio science.Electrical and electronic engineeringMicrowave photonicsFibre optics and optical communicationsNonlinear opticstext::journal::journal article::research article
