ABSTRACT:
A configuration for detecting optical signals of at least one optical channel of a planar optical circuit. At least one deflection device is provided, which couples the optical signals of at least one optical channel at least partly out of the plane of the circuit, and one detection unit is provided, which detects the signals that are coupled out outside the plane of the circuit. Therefore, a simple metrological monitoring of the signals of the optical channels of a planar optical circuit occurs with only slight signal losses and without undesirable crosstalk.
