We investigate coherent polarization dynamics of a neutral exciton in a single InAlAs/AlGaAs quantum dot via time-resolved micro-photoluminescence under quasi-resonant circular excitation. Quantum beats appear in DCP and diagonal linear polarization, while H/V oscillations are suppressed, revealing fine-structure-induced spin precession.
