| Popis: | 103 This study is the use of multi-functional optical fiber processing platform (Vytran GPX-3000) fused 2X2 optic fiber coupler, the characteristics of this coupler is a single mode fiber and hollow core fiber are both dispose in the quartz sleeve and fused bi-conical taper, we use the theory calculation and simulation to analyze and use the multi-functional fiber processing platform to adjust various process parameters, tapering to fit our experimental coupler appearance. And the development of microfluidic optical fiber coupler. The feature of this Coupler is pumped the solution which refractive index is matching the refractive index of single mode fiber as a liquid core of microfluidic optical fiber coupler. The theory is the different materials have different refractive index corresponding to the wavelength slope of the curve, our purpose is to make the refractive index corresponding to the wavelength slope of the curve of the solution and the refractive index corresponding to the wavelength slope of the curve of the single mode fiber matching. According to the coupling theory, when two material of the core have the same refractive index will reach maximum coupling efficiency, at this time all power of the single mode fiber will be coupled to the another fiber liquid core and generate coupling absorption wavelength. We change the refractive index of the liquid fiber core by sensing external factors, and the coupling absorption wavelength is displaced, therefore, this microfluidic optical fiber coupler may be used in a wide range of sensing applications (such as: temperature, concentration, magnetic ...). |
