Photonic integrated circuits, optoelectronic systems and methods

The invention relates to a PIC (1) comprising a plurality of optically interconnected functional photonic blocks (2a-2d) and a reconfigurable optical connection device comprising a plurality of semiconductor-based optical waveguides (3a-3ah) and a plurality of controllable optical switches (4a-4c), the at least one controllable optical switch is configured to be in a first state allowing optical transmission or a second state preventing optical transmission. According to the respective first state or second state of the at least one controllable optical switch, the optical connection device is configured to enable at least one first group of semiconductor-based optical waveguides to provide at least one optical connection between at least two functional photonic blocks and/or a first optical access path to at least one functional photonic block. The invention also relates to an optoelectronic system (100) comprising a PIC and an improved method (200) for determining the overall performance of a PIC according
