Abstract

High spatial resolution time‐resolved photoluminescence has been used to study GaInAs/GaInAsP quantum‐well structures selectively intermixed using the pulsed photoabsorption‐induced disordering technique. Photoluminescence decay measurements at wavelengths ≳1.3 μm were obtained using novel high‐efficiency photon‐counting detectors and were found to correlate spatially with the observed luminescence blue shift in these structures. Results indicate a reduction in the nonradiative recombination time of nearly two orders of magnitude as a result of this intermixing technique.
