From Random Telegraph to Gaussian Stochastic Noises: Decoherence and Spectral Diffusion in a Semiconductor Quantum Dot

Figure 2

Optical spectrum in the presence of a single random telegraph: the Fourier transform of the relaxation function 𝜙₁(𝑡) is plotted for symmetric (𝜂=0) and asymmetric (𝜂=0.3) jump processes for three different values of Ω𝜏_𝑐=5, 1, and 0.2.
