Power-referenced optical fiber refractometer based on a hybrid fiber grating
Fiber Bragg gratings (FBG s) power referenced refractometer tilted- fi ber Bragg gratings (TFBGs)
2011/11/27
An in-fi ber structure for power-referenced re-fractometry based on a hybrid fi ber grating is proposed and demonstrated experimentally. The hybridfi ber grating is formed by superimposing a shortfi b...
Compact refractometer based on extrinsic-phase-shift fiber Bragg grating
Refractometer Extrinsic-phase-shift Fiber Bragg grating Compact sensing structure Large measurement range
2011/5/27
A novel method to measure refractive index of liquids by using an extrinsic-phase-shift fiber Bragg grating(EPS-FBG) is proposed and experimentally demonstrated. The EPS-FBG is obtained by separating ...
Miniature refractometer based on modal interference in a hollow-core photonic crystal fiber with collapsed splicing
photonic crystal fiber modal interference refractometer collapsed splicing
