Abstract :
We proposed an In-line fiber glucose sensor which immobilized the GOx on the surface of no-core fiber by analyzing the MMI signal. Based on the measurement results, the sensitivity of proposed method can be reached 50 mg/dl with the OSA of 0.1 nm wavelength resolution. In addition, different tip of the MMI signal has different sensitivity of the wavelength shifting. In this study, the higher sensitivity of wavelength shifting is around of wavelength of 1450 nm. The smallest wavelength shifting is about 0.1 nm which resulted from the glucose concentration variation of 50 mg/dl.
