Sensors, 18(10), 3285-. doi:10.3390/s18103285 | Series/Report no.: | Sensors | Abstract: | We demonstrate a simple-to-fabricate refractometer based on the inscription of fiber Bragg gratings in a special C-shaped optical fiber. The C-shaped fiber was drawn into shape using a quarter cladding removed preform of a commercial standard single-mode fiber by simple machining. The sensor did not suffer from cross-sensitivity of the refractive index with ambient temperature fluctuations, commonly occurring with many optical fiber refractometers. A refractive index sensitivity of 1300 pm per refractive index unit (RIU) was achieved without employing any additional sensitization techniques such as tapering or etching. | URI: | https://hdl.handle.net/10356/89578 http://hdl.handle.net/10220/46301 |
