We report the carrier dynamics in a spontaneously organized array of quantum wires grown by a novel technique that involves strain induced lateral ordering (SILO). Our cw-photoluminescence (PL) measurements reveal a very strong optical anisotropy associated with these wires, while the time-resolved PL measurements demonstrate a very interesting carrier dynamics due to localization of excitons and slow interwire scattering. The high quality and freedom from defects of the SILO multiple quantum wire array are nicely borne out by the long decay photoluminescence times (∼4 ns).
