Multiple signal representation simulation of photonic devices, systems, and networks

Performance evaluation on high-speed multi-channel CWDM system by using offset-launch method and multi-stage decision feedback equalizer

“…2, its main purpose is to analysis the DFE effect in the three systems: the system without DFE, the system with single-stage DFE, and the system with two-stage DFEs; it should be noted that the system with two-stage DFEs is added by more taps into the second DFE. We find that offset-launch could improve the performance, and the observed patterns are also shown [10]. It shows the effect of using DFE in the system.…”

An Improved All-Fiber Cross-Connect Node for Future Optical Transport Networks

“…Modeling of the transmission performance of OXNs is carried out using Photonic Transmission Design Suite (PTDS version 1.3), a wavelength-domain simulator running on a Windows NT platform [37]. A 4-channel WDM system using the intensity modulated-direct detection (IM/DD) scheme is assumed; the bit rate per channel is set at 2.5 Gbit/s (2 7 − 1 PRBS).…”

Optical clock sources model based on two-section distributed feedback laser with shift-layer

“…), though some numerical techniques have been proposed, one being Transmission Line Laser Modeling (TLLM). VPIcomponentMaker TM Active Photonics is a typical simulator used to analyze semiconductor lasers, including SSP simulation (Lowery et al 2000). But since the internal information in a laser device may not be available in such a commercial tool, the optical clock source design still faces the difficulty of trial-and-error, and the importance of structural parameters has not been compared.…”
