A novel 10-GHz picosecond pulse source consisting of an electroabsorption modulator (EAM) and a subsequent well-designed pulse compressor is demonstrated experimentally. Among its advantages are stable operation and a tunable repetition rate. A 1.1-ps transform-limited ultrashort pulse with no pedestal is obtained. As an illustration of its use, the obtained high-quality pulse is applied to measure other EAMs' optically or electrically induced temporal transmission windows.
