Abstract :
We report, for the first time, the two spectral holes in photocurrent of InAs self-assembled quantum dots embedded in a p-i-n diode irradiated by two different lasers. The estimated homogeneous broadening of less than 30 /spl mu/ eV for InAs QD implies the possibility of wavelength multiplicity of /spl ges/2800 for hole burning memory using QD. The spectral hole width irradiated by single mode YAG laser at 1064 nm showed temperature dependence of exp(T/30.9) in the range from 5 K to 80 K.
