Next-generation high-speed coherent optical communication systems targeting beyond 100-Gb/s per channel, have opened opportunities for innovations in component and subsystem areas that this tutorial will attempt to address, covering photonics, electronics and signal processing technologies.
An optical amplifier followed by a bistable element has been statistically analyzed before. In this manuscript, output noise analysis represents, then signal to noise ratios (SNR) are calculated either for input or output. It will be shown that noise reduction, can be achieved by a proper selection of parameters.
We designed and built a novel all-optical re-timing, re-amplifying, and re-shaping (3R) regeneration system based on terahertz optical asymmetric demultiplexers (TOADs) developed in our laboratory. The system is capable of parallel processing multiple wavelengths, a feature which will significantly improve the scalability of current wavelength division multiplexing (WDM) networks. Performance against...
In conventional optical data transmission schemes, electrical filters and/or optical filters are used to improve the quality of system performance. In this paper, improved design of dense wavelength division multiplexing (DWDM) optical systems is achieved by using a selective electrical filter assignment method. The methodology objective is to optimize system design and mitigate the effects of fiber...
