Abstract

We have demonstrated a high-resolution, low-injection-signal-power optical sampling system using a 20-m-length dispersion-flattened photonics crystal fiber as optical sampling gate, and employing bridge-form low noise optical fiber amplifier. Optical pulse trains with −35 dBm input power and 1.25 ps interval were clearly displayed by using our all optical sampling system. To measure the temporal resolution of system accurately, optical pulse trains from a commercial 40 GHz actively mode-locked fiber laser, were injected into the optical sampling system and an autocorrelator with 5-fs resolution, respectively. 1.02 and 0.83 ps pulse-width were obtained by using our optical sampling system and the autocorrelator, respectively. These measured results show that the resolution of the system is as high as 0.6 ps.
