We present the first demonstration of wavelength selective charge storage (electrons or holes) in In0.5Ga0.5As self-assembled quantum dots with optical readout. Our results demonstrate unambiguously wavelength selective charging with long (≪25 μs) data storage lifetimes and enable us to probe directly carrier excitation processes and potentially electron spin dynamics in micro-ensembles of quantum dots.
