Optical transition edge sensor (TES) detectors which can resolve an energy of a single photon have proven desirable in quantum information and biology. Applications to biology demands high resolution of wavelength. To optimize the TESes, their properties and physical model should be understood well. We report complex impedance and critical current measurements of our optical TESes and discuss their physical model based on the measured parameters.
