Wu, H. Lee, E. Lee] In this paper, a method for generating ultra-short optical pulses in the sub-picosecond regime is presented and numerically demonstrated using a nonlinear nanoporous silicon waveguide followed by a Mach-Zehnder interferometer configuration based on the GaInP photonic crystal waveguide. Research results show that an optimal output pulse with sub-picosecond time duration can be achieved from ~16.65-ps input pulses by selecting suitable system parameters such as initial intensity and waveguide length which will significantly influence the optical properties of the output pulse, including its time domain waveform, frequency spectrum, and phase chirp. The time duration of the corresponding autocorrelation trace can also reach as little as ~1.0-ps at the end of the device. EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg, 2011 Wu J.
