Abstract :
In this paper, we propose a novel and simple predistortion method using schottky diode to compensate the nonlinear characteristics of the DFB-LD for RoF systems. The experimental results show that the enhancement of about 30 dB in the third-order intermodulation distortion (IMD3) and about 10 dB in the spurious-free dynamic range (SFDR) are achieved at 2.4 GHz.
