Abstract:
A nonlinear model for semiconductor lasers is presented based on the Volterra series analysis of nonlinear systems. The semiconductor lasers are composed of the cascaded network of intrinsic laser and parasitic network. The nonlinear transfer functions of the intrinsic laser are derived from the rate equations by the harmonic input method. The nonlinear transfer functions of the parasitic network are acquired by taking into account the main factors that affect the nonlinear behavior in parasitic network for the specific application. Then the total nonlinear transfer function is derived by using the cascading relationship of the nonlinear systems. The second- and third-order harmonic distortion and the third-order inter-modulation distortion are calculated and simulated. The comparison between the analysis and simulation results shows that they are matched closely in a wide frequency range. The influence of the parasitic network on the nonlinearity of the laser increases gradually with the increase of the frequency. The comparison of the error between the Volterra model and the simulation results with different input powers shows that the Volterra model is more suitable for the analysis of the weak nonlinear system. The model is useful for the device characterization and the design of radio-over-fiber(ROF)systems.
