利用大周期光子晶体结构增强InAs/GaAs量子点的激发态发光
Enhancement of excited-state emission of InAs/GaAs quantum dots with large-period photonic crystal
摘要
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.关键词
