Effect of Dispersion on Spectrum-sliced Wdm Systems

Suppression of Four Wave Mixing Based on the Pairing Combinations of Differently Linear-Polarized Optical Signals in WDM System

Data transmission in optical systems and increased transmission distance capacity benefit by using optical amplification wavelength division multiplexing (WDM) technology. The combination of four waves (FWM) is a non-linear effect in the wavelength division multiplex (WDM), when more than two wavelengths of light in a fiber launch will occur. FWM amount depends on the channel, the channel spaci...

Spectrum-sliced Wdm Systems with Optical Preamplifiers

Saddlepoint Approximation for Calculating Performance of Spectrum-Sliced WDM Systems

Spectrum slicing is a novel technique for the implementation of wavelengthdivision multiplexing (WDM). While conventional WDM systems employ laser diodes operating at discrete wavelengths as carriers for the different data channels that are to be multiplexed, spectrum-sliced systems make use of spectral slices of a broadband noise source for the different data channels, thus being economically ...

Spectrum-Sliced WDM Using OOK Transmission

This chapter presents one of the primary contributions of this dissertation: a mathematical model to analyze and evaluate noise-like spectrum-sliced systems which employ conventional PIN receivers, or as proposed in this dissertation, optical preamplifier receivers. As discussed in previous chapters, spectrum-slicing provides a low-cost alternative to the use of multiple coherent lasers for WDM...

Spectrum-Sliced WDM Using FSK Transmission

The focus of this chapter is to consider the case of spectral-slicing when Frequency-Shift Keying (FSK) is used as the modulation scheme. Although the majority of lightwave systems use conventional On-Off Keying (OOK) or intensity modulation, FSK is preferred in certain situations and this chapter will discuss where transmission using FSK may prove advantageous in the context of a noise-like sp...
