摘要：

In some optical communications systems there are advantages to using low duty-cycle pulsed modulation formats such as pulse-position-modulation. However, because of intrinsic limitations of AlGaAs semiconductor lasers, the average power that they can deliver in a pulsed mode of operation is lower than in a cw mode. The magnitude of this problem and its implications are analyzed in this letter, and one possible solution is mentioned.
