unlimited number of equal copies of the signal spectrum is generated. Electrical sampling instead produces a limited number of copies multiplied by a sinc-function. All-optical sampling can be seen as the multiplication of the copies by a Gaussian function. Here we present a very simple method of all-optical sampling which requires neither nonlinear optics nor a mode-locked laser. Besides practical limitations, the only difference to ideal sampling is the fact that a limited number of copies is generated. The idea behind the method as well as first preliminary results for sampling rates up to 90 GSa/s are presented.
