In integrated photonics the testing and characterisation of the components and circuits is of crucial importance to validate ideas, improve designs but also to assess the full photonic system. Because of the many components which can be integrated into one PIC, this is a challenging but rewarding job and as a characterisation and testing engineer this is your turf! You check the PICs as they come fresh from the fab and make sure, they perform as they should. You dynamically develop and adopt test procedures to benchmark the latest layouts and designs.
