Title: | In-line microfluidic refractometer based on C-shaped fiber assisted photonic crystal fiber Sagnac interferometer | Authors: | Wu, C Tse, MLV Liu, Z Guan, BO Lu, C Tam, HY |
Issue Date: | 2013 | Source: | Optics letters, 2013, v. 38, no. 17, p. 3283-3286 | Abstract: | 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. | Publisher: | Optical Society of America | Journal: | Optics letters | ISSN: | 0146-9592 | EISSN: | 1539-4794 | DOI: | 10.1364/OL.38.003283 |
