Abstract:

In this study, the photoluminescence spectra of InAs/GaAs quantum dots material with photonic crystals were investigated by laser diode excitation. The photonic crystals were fabricated in the material of InAs/GaAs quantum dots by laser holography and wet etching method. It was found that the spectra from quantum dots with photonic crystals appeared multi-peak structure; the enhancement and modification to the short-wavelength component were more pronounced than those to the long-wavelength components. The photoluminescence from InAs/GaAs quantum dots was modified by photonic crystals, and the emission from excited states was significantly enhanced.
