  • Utilizing the amorphous-to-crystalline phase transition of ChG around 415 °C.
  • Measuring transmission power loss changes due to ChG phase transition.
  • Demonstrating reversibility by applying an electrical pulse to restore the amorphous phase.

    • Main Results:

    • A significant transmission power drop of over 40dB was observed when Ge40S60 transitioned to its crystalline phase.
    • The sensor demonstrated real-time temperature monitoring capabilities.
    • The reversible nature of the sensor was confirmed by restoring the amorphous phase using electrical pulses.

    Conclusions:

    • The integrated optical sensor based on ChG and silicon waveguides is feasible for real-time temperature monitoring in harsh environments.
    • The sensor's distinct optical loss change upon phase transition allows for accurate temperature detection.
    • The reusability and reversibility of the sensor enhance its practicality for applications such as nuclear reactor cladding monitoring.
