Abstract

We improve and validate the multisection model for a bulk reflective semiconductor optical amplifier (RSOA) as a modulator in radio over fiber (RoF) systems. The RSOA model was developed using the symbolically defined devices (SDD) component under Agilent advanced design systems (ADS) software. An accurate parameter extraction method based on ADS optimization tools is presented. The intrinsic parameters of RSOA are obtained. Here the model is used to assess the static characteristics, harmonic and intermodulation distortions, and transmission performance of RSOA. Simulations have been validated with experimental results providing good agreement.
