General Formulation Of The Scattered Matter Waves By A Quantum Shutter, Yusuf Zi̇ya Umul
Turkish Journal of Physics
The scattering process of matter waves by a quantum shutter is investigated by using the spectrum integral representation. The scattered fields are expressed in terms of the Fresnel function. It is shown that the obtained equation gives the Moshinsky function for a one dimensional problem of the plane wave. Also a general integral representation is derived for two dimensional problems. The scattering of matter waves for some special wave-packets are examined analytically and numerically.

Generation Of Ultrafast Bright And Dark Pulse On Silicon Chip With Integrated Mach-Zehnder Interferometer Configuration, Jianwei Wu, Fengguang Luo
Generation Of Ultrafast Bright And Dark Pulse On Silicon Chip With Integrated Mach-Zehnder Interferometer Configuration, Jianwei Wu, Fengguang Luo
Turkish Journal of Physics
In this paper we propose and simulate ultrafast femtosecond bright and dark pulses, obtained simultaneously at the same center wavelength, based on silicon-on-insulator (SOI) waveguides in Mach-Zehnder interferometer (MZI) configuration; the ultrafast pulsed pump is injected into one MZI's arm and a continuous wave component (CW) is divided equally into the two MZI arms. Numerical results show that properties of the generated bright and dark pulses are strongly dependent on the launching optical powers of both the pump pulse and CW carriers, and on the waveguide length.
