Title :
All-Optical THz Oscilloscope
Author_Institution :
Gigaoptics GmbH, Konstanz
Abstract :
An all-optical oscilloscope based on high-speed asynchronous optical sampling (ASOPS) is realized. It acquires ultrafast optical signals of 1 ns duration with 160 fs resolution at a 10 kHz scan-rate. THz spectroscopy and picosecond ultrasound based thin film characterization are discussed as applications.
