通过干涉技术分析单个 InAs∕InP 量子点在 1300 nm 波长下发射的光致发光。使用连续波光激发测量来自孤立量子点的发射信号的一阶相关函数。通过相关函数的傅里叶变换来评估谱形状，揭示了洛伦兹函数和高斯函数的贡献。 8K 时洛伦兹均匀宽度确定为 28(±4)μeV。
Photoluminescence from a single InAs∕InP quantum dot emitting at a wavelength of 1300nm is analyzed by the interferography technique. The first-order correlation function was measured for emission signals from an isolated quantum dot with continuous wave photoexcitation. The spectral shape was evaluated by Fourier transform of the correlation function, revealing the contributions of Lorentzian and Gaussian functions. The Lorentzian homogeneous width was determined to be 28(±4)μeV at 8K.
