Abstract

A highly sensitive and efficient method for optical sampling utilizing two-photon absorption (TPA) in a semiconductor microcavity was demonstrated. Sensitivity of 0.1 m W², with a temporal resolution of 2 ps was obtained by incorporating the microcavity in an optical sampling setup. It was observed that from the TPA sampling, the optical pulse duration was calculated to be ∼2.4 ps whereas from the second-harmonic generation-frequency resolved optical gating (SHG-FROG) measurement, the pulse width was ∼1.7 ps. It was shown that by reducing the sampling pulse duration, the temporal response of the sampling system could be further improved.
