Dispersion compansation metholds for radio over fiber system

Three different dispersion compensation methods based on Super Structure Fiber Bragg Gratting and injection DFB laser were introduced. Firstly, a SSFBG with nonlinearity group delay spectrum was designed to achieve tunable dispersion compensation. Secondly, a novel approach to realizing single sideband modulation with optimum optical carrier to sideband ratio (OCSR) for maximizing the transmission performance of a radio-over-fiber system is proposed demonstrated based on a strong optical injection-locked distributed feedback (DFB) laser. Lastly, a broadband chromatic dispersion (CD) compensation scheme using an optical phase conjugator (OPC) based on a DFB semiconductor laser is proposed and experimentally demonstrated in RoF links.
