Abstract
Ultra-sensitive all-optical sampling at 1.5 μm using two-photon-absorption in a commercial 1.3 μm quantum-well semiconductor laser has been demonstrated. Using only direct detection of the unamplified two photon absorption photocurrent, a temporal resolution of ~2 ps and a sensitivity of less than 2 mW2 have been achieved
