Abstract
The “spectrum-slicing” technique, employing incoherent light, has been shown to be a highly practical, cheap and hence very attractive proposal for future all-optical networks. In this study, the use of semiconductor optical amplifier gain saturation for intensity noise reduction on incoherent light is further studied in terms of the Relative-Intensity-Noise (RIN), with a view to obtaining the optimum SOA injection current and input power conditions to achieve the best possible intensity noise reduction, in conjunction with OSNR, BER and Q-factor results. The results reported herein give designers knowledge of the best SOA operating conditions to enhance overall system performance, whilst still obtaining signal gain from the SOA.

In present times, developing the capacity of optical fiber networks has become imperative to meet the rapid recent growth in network capacity requirements
Additional schemes are needed in today’s bandwidth hungry world. One such scheme is “Spectrum-Slicing.” (SS). This has been proven as a promising method for generating wavelength channels as optical carriers in which an incoherent light source, such as the Amplified Spontaneous Emission (ASE) from an Erbium-Doped Fiber Amplifier (EDFA) or other broadband source, is spectrally sliced utilizing a bandpass filter (Connelly et al, 2005)
Spectrum-slicing introduces a practical and highly cost-effective solution, utilizing one common light source as opposed to expensive, multiple transmitter lasers operating at different wavelengths and which can be exploited in Wavelength Division Multiplexing (WDM) systems (Lee et al, 1993)
Summary
In present times, developing the capacity of optical fiber networks has become imperative to meet the rapid recent growth in network capacity requirements. In Qikai and Hoon (2014), there was shown a novel offset optical filtering technique to reduce the excess intensity noise of the ultra-narrow spectrum-sliced incoherent light source using a gain-saturated SOA running at 12 Gb/s.
