Influence of Pulse width and Rabi frequency on the Population dynamics of three-level system in two-photon absorption process
Nam-Chol Kim, Myong-Chol Ko, Song-Jin Im +1
We investigate the population dynamics of the three-level system in the two-photon absorption (TPA) process, mainly focusing the influence of pulse width and Rabi frequency on the…
Exciton-Plasmon Coupling Effects on the Nonlinear Optical Susceptibility of Hybrid Quantum Dot-Metallic Nanoparticle System
Nam-Chol Kim, Myong-Chol Ko, Song-Jin Im +1
We have studied theoretically the exciton-plasmon coupling effects on the third-order optical nonlinearity of a coherently coupled hybrid system of a metal nanoparticle and a semic…
Single Plasmon Switching with n Quantum Dots System Coupled to One-Dimentional Waveguide
Nam-Chol Kim, Myong-Chol Ko, Song-Jin Im +1
Switching of a single plasmon interacting with equally spaced quantum dots coupled to one-dimensional surface plasmonic waveguide is investigated theoretically via the real-space a…
