All-solid D-shaped photonic fiber sensor based on surface plasmon resonance

High-Sensitivity Refractive Index Sensor Based on D-Shaped Photonic Crystal Fiber with Rectangular Lattice and Nanoscale Gold Film

“…[15] and [5], about 2,400 and 3,186 nm/RIU respectively, which makes the sensor we proposed a competitive candidate for fiber biosensing applications. However, in the recently published literature [5], the high sensitivity of 6,430 nm/RIU must be obtained by using a supposed kind of a liquid mixed by two organic solutions.…”

“…As we can see in Ref. [15], the author proposed a side-polished fiber optical SPR sensor; the metal film is no longer inside the holes but deposited on the flat surface which is side polished. So the coating can be uniform.…”

“…[5] and Ref. [15], the air holes in the cladding layer of our structure are arrayed in a rectangular lattice. By introducing the rectangular lattice instead of the common regular hexagonal array of air holes, the fiber SPR sensor proposed in this paper performs extremely good.…”

D-shape polymer optical fibres for surface plasmon resonance sensing

“…A single−mode silica microstructured D−shape fibre formed by side−polishing was studied numerically in Ref. 24 for possible applications as an SPR sensor with increased sensitivity obtained by applying a phase sensitive detection method. In Ref.…”

Experimental study of liquid refractive index sensing based on a U-shaped micro-fiber

“…One is to make micro-structure in the fiber such as Fabry-Perot cavity [6][7][8], fiber Bragg grating (FBG) [9][10][11] and optical fiber interferometer [12,13], with which physical quantity can be measured through the changes of optical signals' intensity, phase and wavelength. Another is to make the optical fiber the fiber carrying evanescent field by corroding or drawing a fiber, such as U-shaped fiber [14,15], D-shaped fiber [16][17][18][19] and taped-fiber. Their evanescent field is modulated by external media to measure.…”
