Evanescent field refractometry in planar optical fiber
Evanescent field refractometry in planar optical fiber
This work demonstrates a refractometer in Integrated Optical Fiber (IOF), a new optical platform that planarizes fiber using flame hydrolysis deposition (FHD). The unique advantage of the technology is survivability in harsh environments. The platform is mechanically robust, can survive elevated temperatures approaching 1000oC and exposure to common solvents, including acetone, gasoline and methanol. For the demonstrated refractometer, fabrication was achieved through wet etching an SMF-28 fiber to a diameter of 8 μm before FHD planarization. External refractive index was monitored using fiber Bragg gratings, written into the core of the planarized fiber. A direct comparison to alternative fiber Bragg grating refractometers is made. For which the developed platform is shown to have comparable sensitivity, with the added advantage of survivability in harsh environments.

Abstract
This work demonstrates a refractometer in Integrated Optical Fiber (IOF), a new optical platform that planarizes fiber using flame hydrolysis deposition (FHD). The unique advantage of the technology is survivability in harsh environments. The platform is mechanically robust, can survive elevated temperatures approaching 1000oC and exposure to common solvents, including acetone, gasoline and methanol. For the demonstrated refractometer, fabrication was achieved through wet etching an SMF-28 fiber to a diameter of 8 μm before FHD planarization. External refractive index was monitored using fiber Bragg gratings, written into the core of the planarized fiber. A direct comparison to alternative fiber Bragg grating refractometers is made. For which the developed platform is shown to have comparable sensitivity, with the added advantage of survivability in harsh environments.
