Description
Summary:Code Division Multiple Access (CDMA) technology has shown great success in wireless communication networks. Its counterpart in optical domain, namely Optical CDMA (OCDMA), has unique features such as asynchronous access, bandwidth efficiency and potential network security. The practical challenge of OCDMA today is how to generate and recognize code sequences properly and cost effectively. Moreover, modern optical transmission systems are evolving to dynamic networks; therefore, they require tuning capability. In light of this demand, this research sets an objective to develop tuning systems for fibre grating phase encoders employed in OCDMA networks, which are able to accurately reconfigure the magnitude of phase shift and the operating wavelength, respectively. These tuning systems have attributes of simple, high precision, wide tuning range, and cost efficient.
