Abstract

Waveform and spectrum measurements are indispensable for the characterization of high-speed electronic devices and circuits. Recently, Li et al.¹ demonstrated phase locking of a microwave oscillator to the picosecond laser pulses by the electro-optic (EO) effect and then displayed the waveform by photoconductive sampling via a low-frequency replica. It is interesting to replace the main-frame mode-locked laser used in the previous work with a gain-switched diode laser, which is compact, has high and tunable repetition rate (thus allowing a large number of sampling points per period), and exhibits minimum timing jitter.
