Simultaneous repetition-rate multiplication and envelope control based on periodic phase-only and phase-mostly line-by-line pulse shaping

Abstract

We experimentally demonstrate simultaneous pulse repetition-rate multiplication and periodic pulse-to-pulse peak-intensity control based on optimized periodic spectral line-by-line pulse shaping. Accordingly, the method allows us to generate multiplied pulse trains in which the amplitude of each single pulse in a period can be arbitrarily tailored. The technique is illustrated with the generation of 4×9 GHz arbitrary periodic pulse trains, including binary code patterns, from a 9 GHz uniform input pulse train. Special attention is paid to pulse train generation based on all-pass line-by-line filters.
