Abstract
A new semiconductor laser diode amplifier structure which consists of a semiexponential-linear tapered waveguide active layer has been propo sed to improve the saturation output power. Various characteristic per formances of this device have been analysed based on the step-transiti on approach taking into account the effects of the spatial distributio ns of the carrier density and the optical field. The effects of variou s tapered structures on the gain saturation, intensity distribution an d amplified spontaneous emission noise have also been investigated.
