Abstract :
Highly sensitive fiber-optic refractometer based on cladding-to-core recoupling is proposed by using a weakly tilted fiber Bragg grating combined with a lateral-misaligned splice structure. Reflection spectrum with two well-defined bands performs a linear response for acceleration measurement, combining with temperature immunity and power self-calibration property.
