We demonstrate simultaneous spatial and arbitrary temporal pulse-shaping with a picosecond Yb-doped fiber laser system generating an output power > 10 W. By using a self-developed feed-back control algorithm on a single polarization optical pulse shaper, we obtained arbitrary complex pulse structures in the time domain with high accuracy and at high power level. Meanwhile, the pulse shaping in...
In this paper, a pulse width compression scheme for optical time division multiplexing (OTDM) system based on supercontinuum (SC) is proposed. After injecting a high power narrow line-width pulse width laser into high nonlinear fiber (HNLF), the pulse width has been obviously narrowed. This demonstration suggests that the pulse width compression effect of SC could be used in free-space OTDM system.
By solving Schrodinger equation in standard Split-Step Fourier Transform (SSFT) method, the NRZ, 33%RZ, 50%RZ, CSRZ, DPSK, 33%RZ-DPSK, 50%RZ-DPSK and CSRZ-DPSK were simulated in 40G bit/s single channel transmission system with the influence of dispersion, nonlinearity and polarization mode dispersion. The simulation results show that CSRZ has better performance than the other modulation formats in...
