Abstract

We describe a wide band optoelectronic device for short electrical single pulses sampling. The devices are made with microstrip propagation lines on a sapphire substrate and ultra-rapid photoconductive switches are integrated on the same substrate (synchronously to the electrical pulse, a femtosecond laser pulse is used to switch the photoconductive elements). The switches are made of thin semiconductor films deposited by molecular beam epitaxy at low temperature. The propagation on the stripline structure has been simulated and characterized. A 16 channels prototype with 18 ps sampling step has been realized and tested. The analysis of one sub- 50 ps electrical transient has been demonstrated. This type of device should easily allow to reach sampling steps down to 5 ps.
