Abstract :
Software for calculation of gain-current relation, gain saturation and light-induced refractive index change in diode amplifiers and lasers is developed. Three distinct types o filamentation in tapered (flared) amplifiers are found and their dependence on the amplifier geometry is investigated. Practica guidelines for filamentation suppression are suggested.
