Abstract
The invention relates, inter alia, to a photonic component (), which has an interference device (), which has at least one input and at least a first and a second output. According to the invention, the component also comprises: a first grating coupler (GC), which has a first and a second grating coupler output and is connected to the first output of the interference device by means of a grating coupler input, a second grating coupler (GC), which has a first and a second grating coupler output and is connected to the second output of the interference device by means of a grating coupler input, a first photodetector (PD), which is connected to the first grating coupler output of the first grating coupler, a second photodetector (PD), which is connected to the first grating coupler output of the second grating coupler, and a control device (), which is connected to the first and second photodetectors and, on the basis of the photo signals (I, I) of the two photodetectors or an evaluation signal formed by means of the photosignals, forms at least one control signal (ST, ST) for controlling the interference device, wherein the first and second grating couplers are arranged, in particular integrated, in the same chip level (E) of a chip () of the component and wherein, in the case of the first and second grating couplers, the second grating coupler outputs each form a coupling path out of the chip level, namely at an angle of between 70 and 110 degrees to the chip level.
