Abstract
A simple method is presented for determining the minimum feedback level required for the onset of instability and chaos in semiconductor laser diodes. Using this method, the positions of the pair of dominant system poles in the s-plane are found for varying levels of feedback. This analysis determines the feedback level required to send the system unstable. The results are applicable for both long and short external cavities. The method is ideally suited to the prediction of system stability from measurements of microwave modulation response or relative intensity noise (RIN) spectrum, since it only requires knowledge of the natural frequency and damping frequency of the dominant s-plane poles of the laser diode without optical feedback.
