  • Abstract The purpose of this study is to use multi-functional optical fiber processing platform produce 2X2 single-mode fiber coupler, and use theory and simulation to analyze, as the basis of the starting, development of novel fused coupler device. The characteristics of this coupler is a 2x2 single-mode fiber coupler in which a single-mode fiber replaced by our laboratory to manufacture the capillary fiber. The use of this coupler is similar to the use of single-mode fiber refractive index of the solution pumped capillary fiber to a liquid switch fiber coupler. We know that the refractive index decreases as the wavelength increases, the slope of the different materials for this change is different, and due to the different materials, the thermal coefficient of refractive index is different, so we can be found in the case of different temperatures, the refractive index of the two materials are equal, and other wavelength is different, therefore, only when the same refractive index of the wavelength in order to fully coupled. The advantages of this coupling is temperature control of its maximum coupling wavelength range, and the capillary fiber core is liquid, we can use this measurement technique for the development of liquid, if the later then the single-mode fiber to replace the other refractive index different fiber, you can use this method to measure the other liquid.
    Next, use simulation software to simulate this coupler, the coupling wavelength and coupling efficiency values of the change in refractive index different cases, in order to facilitate the produce this novel fused coupler device.
