Abstract

We investigate the direct use of two-photon absorption (TPA) for ultrafast all-optical switching by measuring the switching intensities, recovery times, and modulation depths obtainable from TPA in a waveguide. The measurements were performed on a 600-μm-long, antireflection-coated, p-i-n ridge waveguide. The waveguide was 0.27 μm thick and had five 6-nm-thick InGaAs quantum wells (1.48-μm peak absorption wave length) separated by 10-nm-thick InGaAsP barriers (1.15-μm band-gap composition). Figure 1 shows the experimental setup. Pulses of-200 fs FWHM were split 200:1 for the pump-probe measurements.
