  • Abstract Purpose of this study is to use multi-function optical processing platform production 2X2 single-mode fiber coupler, and in theory, and simulation to analyze the development of micro-fluidic optical fiber coupler, the use of adjustable diameter fiber splicing platform developed fiber coupler, set different process parameters, this coupler is characterized by the 2x2 single-mode fiber coupler in which a single-mode fiber into its own pumping system laboratory hollow core fiber coupler purpose of this is the use of single-mode fiber and similar hollow core index solution was pumped liquid optical fibers together to achieve a fiber coupler. Material with the refractive index due to the general increase and decrease the wavelength, and different materials for this change with different slopes, and in accordance with the coupling theory, only the two are the same refractive index to achieve maximum coupling efficiency, and if the optical fiber in the empty tube and single-mode fiber core poured liquids of different materials, the refractive index reaches the focus will result in only a single wavelength of maximum coupling efficiency can be achieved, while other wavelengths are different in refractive index due to rapid decline in coupling efficiency. This coupling has the advantage that the temperature control can be coupled to the maximum wavelength shift, and the his coupler is characterized by the 2x2 single-mode fiber coupler in which a single-mode fiber into its own pumping system laboratory hollow core fiber coupler purpose of this is the use of single-mode fiber and similar hollow core index solution was pumped liquid optical fibers together to achieve a fiber coupler. optic core is a liquid, we can use this to measure the concentration of a liquid, if the single mode fiber and then later be replaced by other different refractive indices the optical fiber can be measured with this method other liquids.
      Next, using the simulation software to simulate such a coupler coupling the coupling efficiency of the wavelength and the refractive index changes in the value of different situations, so that the production of micro-fluidic optical fiber coupler.
