Abstract

While optical fibre-based sensors are well-developed and applied at various measurements, it is fragile. Therefore, packaging of the sensor is an important aspect. In this paper, packaging schemes for singlemode-multimode-singlemode optical fibre are observed numerically and experimentally. The effect of material variation to the sensitivity of temperature sensor is observed between 25-100 °C. Packaging thickness and shape variation is also taken into consideration. Both intensity-based interrogation and wavelength shift method show that the sensitivity of the sensor increases when packaging is applied, compared to the bare SMS sensor. The application of PTFE as packaging increases the sensitivity of SMS sensor, from 0.0103 dB/°C to -0.0590 dB/°C, about 5.7 times higher.
