A fiber-optic temperature sensor has been fabricated by first sputtering a silicon film onto the end of an optical fiber. The approximately one-micrometer thick silicon film serves as a Fabry-Perot etalon whose resonant wavelengths change as a function of temperature. The silicon film is annealed in order to stabilize its structure. This will provide a sensor with acceptable long term stability. The use of wavelength encoding fiber optic sensors provides a high degree of immunity from cable and connector effects. The benefits of this technology include reduced volume and weight, reduced cost, and improved reliability.
