Implications of laser nonlinearity on the performance of integrated analog wireless/optical networks: modeling, simulation and measurements

In this paper, we present a semiconductor laser model to accurately predict the dynamic operations and the nonlinear distortion in a directly modulated semiconductor lasers. We introduce a new implementation technique for the proposed model that provides a compelling incentive for the performance assessment and enhancement of the analog wireless/optical transceivers using Agilent Advanced Design System (ADS) CAD tool. A detailed comparative experimental and simulation study of the dynamic operation and the nonlinear distortion in laser diodes are used to verify the accuracy of the proposed model for analyzing the performance of the analog optical transmitters. The measured results, such as harmonic and intermodulation distortion levels, are in good agreement with the simulation results.
