Abstract
The invention relates to a method for homogenization of the output beam profile of a multimode optical waveguide (10). The method comprises the following method steps: The invention furthermore relates to a device for carrying out the method. At least one splitting device (14) which is designed to split input radiation (2) over two or more beam paths (I-IV), at least one modulator (16) which is designed for modulating the radiation in at least one of the beam paths (I-IV), and at least one superimposition device which is designed for combining the beam paths (I-IV) by superimposing the modulated radiation and for directing the superimposed radiation onto the input (9) of the multimode optical waveguide (10), are components of a photonic integrated circuit (3) according to an embodiment of the device.
