Abstract
The instant invention relates to a method and a device for optical phase modulation by means of semiconductor amplifiers. In this case an optical semiconductor amplifier comprises optical waveguides 10, which rise over its length and change in its lateral extension, so that light supplied at the optical inlet 11 undergoes an amplification on its way to the optical outlet 12.
