Pulse generation and compression using an asymmetrical porous silicon-based Macha€“Zehnder interferometer configuration

摘要

We propose an asymmetrical Macha€“Zehnder interferometer (MZI) for efficient pulse generation and compression using porous silicon (PS) waveguide, fibre delay line and couplers. We show a pulse compression of about 0.4 ns at the output port with third-order super-Gaussian input pulse in a??2 ns time duration and a??40.3 W peak power level. Also, we show the possibility of obtaining compressed single- or double-pulse with judicious choice of various parameters like input peak power, delay time and input pulse width.
