Burst shaping in a fiber-amplifier chain seeded by a gain-switched laser diode

Petelin, Jaka (author), Podobnik, Boštjan (author), Petkovšek, Rok (author)

A low-power source, such as a gain-switched laser diode, usually requires several amplification stages to reach sufficient power levels. When operating in burst mode, a correct input burst shape must be determined in order to compensate for gain saturation of all amplifier stages. In this paper we report on closed-form equations that enable saturation compensation in multiamplifier setups, which eliminates the need for an adaptive feedback loop. The theoretical model is then evaluated in an experimental setup.
