Abstract :
In this paper, we use photonic crystal microcavity to enhance and control the photoluminescence from Ge self-assembled quantum dots. The microcavities are formed by introducing defects into two dimensional PhC slab on silicon-on-insulator (SOI). Strong resonance luminescence is observed at room temperature and the wavelengths of the luminescence peaks are adjusted by changing the PhC parameters
