The objective of this thesis is to study the dynamic properties of laser diodes and the compensation for the nonlinearities of laser diodes based on the theory of Volterra series. In the first part of this thesis, an analytical expression in Volterra series is discussed to depict the nonlinear distortion of laser diodes up to the third order. The simulation results of this analytical method show that Volterra series model improves the accuracy of the description of the nonlinearity of laser diodes in comparison with small-signal analysis model. In the second part, the p^th-order inverse theory is introduced to compensate the lasers' nonlinear distortion. The compensation scheme is constructed and the simulation of the system is conducted in this thesis. The result shows that the laser nonlinear distortion can be compensated by using this technique. / Thesis / Master of Applied Science (MASc)
