Analysis of deterministic modes of optical modulators laser diode affected by external harmonic signals

Semiconductor laser diodes are the main part of optical modulators. Semiconductor injection laser diode affected by external microwave modulating signal is a complex nonlinear oscillation system. Such non-liner systems are usually described by some systems of well-known differential equations. In the article the non-linear oscillation systems were analyzed by method of Poincare maps and different modes of semiconductor laser diodes under microwave modulating signal influence were described. Results of numerical experiments are discussed.
