Y. Sugiyama et al., OBSERVATION OF SPECTRAL HOLE-BURNING IN PHOTOCURRENT SPECTRUM OF INASSELF-ASSEMBLED QUANTUM DOTS EMBEDDED IN PIN DIODE, Electronics Letters, 33(19), 1997, pp. 1655-1657
The spectral hole burning of InAs self-assembled quantum dots (QDs) em
bedded in a pin diode has been observed for the first time. The spectr
al hole depth increases as the electric field is increased. By numeric
al fitting to experimental results, the possibility of wavelength-doma
in multiplicity in optical memory by using InAs QDs is shown.
