Abstract: The future development of high-speed optical data channels, operating at individual data rates in excess of 100Gbit/s, will require a sensitive and ultra-fast method for pulse measurement [1]. Current high-speed signals are usually characterized using a fast photodetector in conjunction with a high-speed oscilloscope, but are limited to maximum data rate of approximately 40Gbit/s. An alternative is to employ all-optical sampling techniques based on ultra-fast optical nonlinearities present in optical fibres, crystals and semiconductors. One such nonlinearity is the optical-to-electrical process of Two-Photon Absorption (TPA) in a semiconductor [2].
