Sampling is the first step to convert an analogue optical signal into a\ndigital electrical signal. The latter can be further processed and analysed by\nwell-known electrical signal processing methods. Optical pulse sources like\nmode-locked lasers are commonly incorporated for all-optical sampling, but have\nseveral drawbacks. A novel approach for a simple all-optical sampling is to\nutilise the frequency-time coherence of each signal. The method is based on\nonly using two coupled modulators driven with an electrical sine wave, allowing\nsimple integration in appropriate platforms, such as Silicon Photonics. The\npresented method grants all-optical sampling with electrically tunable\nbandwidth, repetition rate and time shift.\n
