Abstract

The present invention relates to a driving circuit, and the use of a drving circuit, for the driving of an electro absorption modulator. The driving circuit comprises a high frequency emphases electrical circuit to compensate for a low frequency emphasis of the electro absorption modulator. Preferably, the high frequency emphases electrical circuit comprises at least a first filter having a zero in the range of 0.3 - 1.2 Ghz and a pole at a 10 to 50% higher frequency.
