|Title:||Femtosecond compensated pair-pulses generation with nonlinear SOI-MZI waveguides|
|Abstract:||In this paper, we propose and simulate the generation of femtosecond compensated pair-pulses (bright and dark pulses), obtained simultaneously at the same center wavelength. The proposed configuration is based on a silicon-on-insulator (SOI) Mach-Zehnder interferometer (MZI) waveguide. The ultrafast pair-pulses are pumped at the mid-wave infrared wavelength (MWIR) injected in one arm of MZI, and a continuous-wave (CW) at the near infrared wavelength (specific communication wavelength) is launched from the other arm of MZI and divided equally into the two MZI arms. Numerical results show that femtosecond compensated pair-pulses with little pedestal shoulders in optical communication window can be simultaneously generated. In addition, the output properties, including the extinction ratio (ER) and contrast of compensated pair-pulses, are studied. The relation between the launching optical powers and the length of the Nonlinear SOI-MZI Waveguides are also explored. Such a work is helpful to dual binary code optical communication systems, opto-electronic devices and spectroscopy, etc.|
