| Popis: | Optical fiber bend sensor with photonic crystal fiber (PCF) based Mach–Zehnder interferometer (MZI) is demonstrated experimentally. The results show that the PCF-based MZI is sensitive to bending with a sensitivity of 3.046 nm/m−1 and is independent on temperature with a sensitivity of 0.0019 nm/°C, making it the best candidate for temperature insensitive bend sensors. To that end, another kind of bend sensor with higher sensitivity of 5.129 nm/m−1 is proposed, which is constructed by combining an LPFG and an MZI with zero offset at the second splice mentioned above. |
