Paper Abstract

Optical sampling with a traveling-wave semiconductor laser amplifier driven by short electrical current pulses is experimentally investigated for the purpose of designing a simple, compact and sensitive solid-state sampling optical oscilloscope.The temporal resolution of about 350 ps with the chip gain of 10 dB is demonstrated. The minimum detectable power is about 45 nw, which corresponds to input optical energy less than 0.01 fRpuise. The larger chip gain of 23 dB with aperture time of 110 ps for optical sampling is obtained if the laser amplifier is driven near the dynamic threshold level, however unexpected output signals where the intensity variation is inverted are observed.
