Optical transition edge sensor (TES) detectors which can resolve an energy of a single photon have proven desirable in quantum information and biological imaging. To optimize the TESes, their physical models should be understood well. Behaviors of the critical current of the detectors will reveal which model our TESes follow. We report critical current measurements of our optical TESes.
