Abstract
The invention relates to an electrical circuit for a directly modulated semiconductor radiation source having a semiconductor radiation source, to which a modulated current is supplied in a manner dependent on a digital data signal, the falling signal edge of said current exhibiting peaking. According to the invention, provision is made of circuit means which are connected to an electrical contact point of the circuit and which reduce peaking of the falling signal edge when a predetermined value of the forward voltage across the semiconductor radiation source is undershot. This allows higher data rates to be achieved.
