High-quality nondoped T wires in a T-wire laser structure were fabricated using cleaved-edge overgrowth with molecular-beam epitaxy on the interface improved by a growth-interrupt high-temperature anneal. Micro-photluminescence and photoluminescence excitation measurements on the T wires were performed using a continuous wave titanium-sapphire laser. The observed PLE spectrum of the T wires showed strong ground-state-exciton peak and a small continuous absorption band with an onset at 11 meV above the peak.
