Semiconductor Diode Laser Dynamics

Abstract

<p> This report is a study of the dynamic properties of semiconductor laser diodes. The measurement of some important laser diode parameters necessary for dynamic behaviour prediction is described. The relaxation oscillation behaviour for laser diodes pumped with nanosecond time scale current pulses is predicted using both an approximate analytic solution and computer simulations. This predicted behaviour is compared with experimental results. Dynamic experiments with an external cavity for extra optical feedback and a regenerative loop for optoelectronic feedback are also described and discussed. Details of the experimental setups and techniques used are given. </p>
