Four Wave Mixing in a Highly Nonlinear Media

This work presents a comprehensive study of the four wave mixing (FWM) effect in the highly nonlinear fibre (HNLF) and semiconductor optical amplifier (SOA); and their applications. The nonlinearity parameters such as zero-dispersion wavelength (ZDW), chromatic dispersion (CD) and nonlinear coefficient of HNLF has successfully investigated by using several FWM techniques. Results from all techniques have been achieved approximately similar to the manufacturer specification. This technique is then employed for the measurement of the FWM power and FWM efficiency in a SOA, in addition to the gain performance, which is measured using conventional methods. Based on these parameters, a good agreement between experiments and numerical has been obtained. This characterization is important for nonlinear application such as wavelength conversion, fibre optic parametric amplifier (FOPA) and multiwavelength fibre laser. Wavelength conversion is a key for wavelength division multiplexed (WDM) networks. Wavelength converter based on HNLF and SOA are promising candidates for implementing wavelength conversion.
