Paper Abstract

Two-photon absorption of 1.55 μm light in quantum well InGaAsP/InP laser heterostructures has been measured. Nonlinear response as high as 0.78 nA/mW2 has been found. Minimal detectable peak power 60 μW allows using this kind of semiconductor waveguide as a detector in optical autocorrelator to investigate low-power signal.
