Abstract
A broadband chromatic dispersion (CD) compensation scheme using optical phase conjugation (OPC) based on a DFB semiconductor laser is proposed and experimentally demonstrated in analog photonic links (APLs). The DFB laser acts as a nonlinear medium to induce four-wave mixing and a pump laser simultaneously. Compared with the conventional OPC based on a semiconductor optical amplifier or a dispersion-shifted fiber, an extra pump laser is no longer required. Experimental results show that the power fading caused by the CD in a 50.4-km APL can be compensated with a 3-dB bandwidth up to 33 GHz. Meanwhile, the spur-free dynamic range is enhanced with 12.6 dB · Hz 2/3 ; the transmission performance is also improved.
