Transition-edge sensors (TESs) are promising micro-calorimeters for applications in the field of quantum information, quantum computation and metrology due to their photon-number resolving capability. Quantum efficiency (QE) is fundamental in single-photon detection and it should be as high as possible. For this reason the coupling between the light source and the sensor plays a crucial role.
