In-line microfluidic refractometer based on C-shaped fiber assisted photonic crystal fiber Sagnac interferometer

We propose and demonstrate a highly sensitive in-line photonic crystal fiber (PCF) microfluidic refractometer. Ultrathin C-shaped fibers are spliced in-between the PCF and standard single-mode fibers. The C-shaped fibers provide openings for liquid to flow in and out of the PCF. Based on a Sagnac interferometer, the refractive index (RI) response of the device is investigated theoretically and experimentally. A high sensitivity of 6621 nm/RIU for liquid RI from 1.330 to 1.333 is achieved in the experiment, which agrees well with the theoretical analysis.Department of Electrical EngineeringDepartment of Electronic and Information Engineerin

Fiber optic pressure sensor based on polarization-maintaining photonic crystal fiber for downhole application

20th International Conference on Optical Fibre Sensors, Edinburgh, 5-9 October 2009We experimentally demonstrate a high pressure sensor based on a polarization-maintaining photonic crystal fiber (PMPCF) with Sagnac loop configuration for downhole application. The pressure sensitivity of the proposed sensor is 4.21 nm/MPa and 3.27 nm/MPa at ∼1320 nm and ∼1550 nm respectively. High pressure measurement up to 20 MPa has been achieved in our experiment. The sensor also shows reduced temperature sensitivity, making it an ideal candidate for pressure sensing in harsh environment.Department of Electrical EngineeringDepartment of Electronic and Information Engineerin
