Abstract :
The rate equations of a semiconductor laser, with feedback due to optical reflections, are solved numerically under the condition of direct intensity modulation. The nonlinear distortion induced by the laser diode are investigated under the conditions of small and large signal modulations. The results show that for large signal modulation, the effect of optical feedback may be very small
