Dual-wavelength Highly-sensitive refractive index sensor
Optics Express, 2017 We report and demonstrate a highly-sensitive refractive index (RI) sensor based on a linear-cavity dual-wavelength erbium-doped fiber laser (DWEDFL). The optical spectrum of the laser varies as the external environmental RI changes from 1.3 to 1.335.

Ultrasensitive tapered optical fiber refractive index glucose sensor
Scientific Reports, 2023 AbstractRefractive index (RI) sensors are of great interest for label-free optical biosensing. A tapered optical fiber (TOF) RI sensor with micron-sized waist diameters can dramatically enhance sensor sensitivity by reducing the mode volume over a long distance.

Numerical investigation into a surface plasmon resonance sensor based on optical fiber microring
Photonic Sensors, 2017 A reflective surface plasmon resonance (SPR) sensor based on optical fiber microring is proposed. In such a sensor, plasmons on the outer surface of the metallized channels containing analyte can be excited by a fundamental mode of a thin-core fiber (TCF)

Universal scaling of plasmonic refractive index sensors
Optics Express, 2013 We establish experimental and numerical evidence that the refractive index sensitivities of various subwavelength plasmonic sensors obey a simple universal scaling relation that the sensitivities linearly increase with λm/neff (where λm is the resonant wavelengths and neff is the effective refractive index of the environment) and exhibit a slope equal ...
