Abstract
Software for calculation of gain–current relation, gain saturation, light-induced refractive index change and light propagation in diode amplifiers and lasers is developed. Three orders of filamentation are found in tapered (flared) amplifiers within the typical ranges of the parameters. While the 1st order is caused by small external perturbations, the 2nd and 3rd orders are generated by the optical beam itself. The causes of the different types of filamentation are elucidated and their dependence on the amplifier geometry is investigated. Practical guidelines for filamentation suppression are suggested.
