摘要： The present invention relates to an apparatus (1), a system (2), a method (200), and a computer program for synthesizing at least one targeted broadband electromagnetic signal (60). Herein, the apparatus (1) comprises
- at least two electromagnetic signal generators (10, 11), wherein the electromagnetic signal generators (10, 11) are configured to provide at least two tributary electromagnetic signals having spectra that overlap at least partially;
- at least one signal-combining element (50), wherein the at least one signal-combining element (50) is configured to merge the at least two tributary electromagnetic signals into at least one combined electromagnetic signal;
- at least one signal-detecting element (90), wherein the at least one signal-detecting element (90) is configured to generate at least one detection output signal (100) by detecting at least a portion of at least one of the at least one combined electromagnetic signal;
- at least one controlling element (110), wherein the at least one controlling element (110) is configured to extract signal information about at least one of a relative amplitude or a relative phase with which the at least two tributary electromagnetic signals are merged into the at least one combined electromagnetic signal from the at least one detection output signal (100);
- at least one actuating element (30), wherein the at least one actuating element (30) is configured to modify at least one of the amplitude or the phase of at least one of the at least two tributary electromagnetic signals based on the signal information,
wherein modifying the at least one of the amplitude or the phase of the at least one of the at least two tributary electromagnetic signals is performed in a manner that at least one of the at least one combined electromagnetic signal corresponds to the at least one targeted broadband electromagnetic signal (60).

摘要： Second-order optical nonlinear material arranged on a substrate (10; 21, 22, 23; 50, 51), wherein the second-order optical nonlinear material (14; 24; 45; 52) comprises at least two different materials (A; B; C) arranged in layers on the substrate (10; 21, 22, 23; 50, 51). The layers are arranged on each other in a predetermined order based on the type of material and/or orientation of the layer. The predetermined order is chosen so that the layers of the at least two different materials possess no macroscopic centrosymmetry with respect to their material and/or orientation.
