Abstract: Suspended core fiber (SCF) is one of the key classes of microstructured optical fibers (MOFs), which incorporate three air holes within their cross-section. The holes within SCFs can offer significant overlap between guided mode of the fiber and the air holes and can be used to control the interactions between guided light and matter located within the holes. We report a silica optical fiber sensor using quantum dot (Qdot) filled Suspended Core Fiber (SCF). We explored the dipping sensing of SCF using shorter excitation wavelength and numerically and experimentally proved that shorter excitation wavelength gives a better fluorescence excitation and capture. In addition, we found a clearer distinction between glass fluorescence and Quantum Dot fluorescence which can reduce the crosstalk of them and increase the sensitivity of SCFs. Selective filling method to investigate the guidance performance concludes that filling all the holes in the SCF has the best outcome.
