In this paper we present two software tools for the simulation of electron multiplication processes in radio frequency (RF) waveguides. The electric discharges are caused by the multiplication of a small initial number of electrons. These are accelerated by the RF field and produce new electrons either by collisions with the walls of the waveguide (ripping new electrons from them), or by ioniza...

We consider a semiconductor quantum-well placed in a waveguide microcavity and interacting with the broadband squeezed vacuum radiation, which fills one mode of the waveguide with a large average occupation. The waveguide modifies the optical density of states so that the quantum well interacts mostly with the squeezed vacuum. The vacuum is squeezed around the externally controlled central freq...

in order to implement an integrated optical quantum circuit, designing waveguides based on the quantum box is of prime importance. to do this we have investigated optical waveguide both with and without optical pumping. the rate of absorption and emission using an array of algaas/gaas quantum box core/shell structure in the optical waveguide with various pumping intensities has computed. by con...

In this work we study the surface scattering mechanisms from rough surfaces of a multimode quasi-1D waveguide (conducting quantum wires). The square-gradient scattering mechanism, which was missed in existing studies of the transport through surface-corrugated waveguides, is discovered. The main attention is paid to the interplay between the new mechanism and the known one, as well as its effec...

Abstract Some vacuum chambers in particle accelerators perform a waveguide- or resonator-like behavior due to their unique geometries. Electron multipacting caused by such structural property might be able overwhelm the classical beam-induced multipacting. This article shows that wakefields of beams could stimulate resonant modes chamber with near-rectangular waveguide shape and accordingly ind...

The electronic distribution in quantum cascade lasers (QCLs) arises from the detailed balance between the injection and the energy relaxation rates, i.e. interand intra-subband electron-electron, electron–LO phonon, electron-impurity, and interface roughness scattering. In mid-infrared QCLs the electron-electron and the electron-phonon interactions lead to a non-equilibrium thermalized distribu...
