Abstract
The dynamical behaviour of a double tapered semiconductor laser diode has been studied numerically using a modified beam-propagation method. By examining the near and far-field mode evolution during gain-switch ed operation, we find that the optical power threshold for filament fo rmation in a double tapered device is significantly higher compared wi th standard broad area stripe devices. Optimization for filament-fi ee high power operation from double-tapered devices has also been carrie d out.
