Abstract. The electronic layer multicast is going to face the speed and capacity bottleneck of the future optical data networks. Transparent optical wavelength multicast by multi-wavelength conversion is an effective way of achieving data multicast in the optical domain without any optical-electronic-optical conversion. In this paper, two multiple wavelength conversion technologies for 10 Gb/s data rate are investigating and discussed. The first technology is based on cross-phase modulation in a semiconductor optical amplifier -MachZehnder interferometer, and the second is based on four-wave mixing in a dispersion-shifted fiber. We present the simulated performance comparison of two approaches obtained using VPItransmissionMaker TM WDM simulator. Afterwards, we analyze these results in comparison with our previous experimental results of the same schemes.

“…Not only a huge amount of optic-electronic-optic (OEO) transponders and electronics can be saved for the same function, new applications are also emerging from this possibility. In particular, optical layer WDM wavelength multicast [3][4][5][6] and Grid networking [7] are becoming both technically feasible and commercially applicable.…”

“…The mostly investigated MWC methods use the following techniques: four-wave mixing (FWM) [8,9], cross-phase modulation (XPM) [3][4][5], cross-gain modulation (XGM) [6,7], cross-absorption modulation (XAM) [10], and fast nonlinear polarization switching (NPS) [11]. Among these, XPM multi-wavelength converters (MWCRs) based on a semiconductor optical amplifier (SOA)-Mach-Zehnder interferometer (MZI) excel the others by offering a great combination of advantages: satisfactory and leveled conversion efficiency across wide conversion bandwidth featured by the SOA gain spectra, simultaneous conversion of a considerable number of channels, wavelength flexibility, high operation speed, supporting both RZ and NRZ data format, power economical, commercial product availability, compactness, and integration potential.…”

We experimentally demonstrate regenerative all-optical wavelength multicast by simultaneous multi-wavelength conversion of 10 Gb/s non-return-to-zero signals to four ITU 100 GHz spaced channels with a receiver sensitivity improvement of 1.84 dB and less than 0.14 dB difference among all the multicast channels, using a single commercial monolithically integrated SOA-MZI. The multicast device also exhibited about 22 dB optical signal-to-noise ratio enhancement for all the converted channels compared to the original signal channel without wavelength conversion. Our experiment for the first time revealed the regeneration properties of a SOA-MZI device for WDM wavelength multicast purposes, and proved the excellent performance of a simple scheme for various future network and system applications, such as all-optical wavelength routing and grid networking.

scheme, standard FDTD, and FDTD (2, 4). Also, both fourth-order schemes permit a coarser discretization than other schemes for a given error bound, which, in turn, allow faster computation time and the storage of less data. CONCLUSIONThe proposed symplectic scheme is more efficient in the calculations at the same computational cost than the mostly used fourthorder symplectic scheme in Refs. 2 and 3, and provides a new approach for solving large computational domain electrodynamics problems.
