Background-Free Optical Sampling System Using Si Avalanche Photodiode as Two-Photon Absorber

The introduction of a double-chopping scheme eliminates the background level in the optical sampling system, where a Si avalanche photodiode acts as a two-photon absorber. We successfully demonstrate background-free optical sampling of 40-GHz and 160-GHz pulse trains.
