Résumé

Dealing with the increase of digital optical data transmission rates requires innovative approaches for stretching or compressing optical waveforms beyond the bandwidth limitations inherent to conventional electro-optical systems. To this aim, photonic platforms exploiting ultrafast nonlinear phenomena have been successfully applied to the temporal stretching of optical waveforms. However, the inverse process, the temporal compression of arbitrary light-waves, has remained largely unexploited so far. Here, we present an experimental demonstration of extreme temporal compression of in-fibre waveforms, including non-trivial on-demand time reversal. The method is based on counter-propagating degenerate four-photon interaction in birefringent optical fibres. We demonstrate the performance of this system by generating ultrafast replica of data packets with record temporal compression factors ranging from 4,350 to 13,000. This approach is scalable and offers great promise for ultrafast arbitrary optical waveform generation and related applications.
