The second and third-harmonic generation of modified Gaussian quantum dots under influence of polaron effects

Reza Khordad, Hossein Bahramiyan

In this paper, we have studied the effect of electron–phonon (e–p) interaction on the second harmonic generation (SHG) and third harmonic generation (THG) of modified Gaussian quantum dots within the framework of the compact density matrix approach and iterative method. We have obtained the energy eigenvalues and their corresponding eigenfunctions of the system without e–p interaction and under the influence of electron–LO phonon, electron–SO phonon, and electron–LO + SO phonon interaction. It is found that the effect of the electron–phonon interaction has a great influence on the second and third harmonic generation of the system. The effect of electron–SO phonon on the SHG and THG is greater than the electron–LO phonon. The electron–LO + SO-phonon interaction has the largest contribution to the SHG and THG.

Optical bistability in an electron-hole system: the effect of phonons

S. Mohapatro, Sukanta Kumar Tripathy, G. S. Tripathi +1 more

We consider an electron-hole system illuminated by a laser and show that the system shows bistable and multistable behaviours. The mechanisms responsible for these behaviours are discussed in terms of excitonic and phonon interactions. It is found that both the excitonic and the phonon effects contribute to the multistability in the system. With an increase in the strength of the phonon interactions, the system passes from a phase of multistability to a phase of bistability; the reverse happens as the strength of the electron-hole interaction increases.
