This article discusses the development of fiber optic refractometers of paral-lel type based on two Bragg gratings with the pi-phase shift, one of which is etched in the contact zone with the test substance. The possibility of addi-tional control of tensile/compression deformation of the structural elements, in which the test substance is, by third grating, incorporating in the refrac-tometer, and increase of measurement resolution by creating ring gratings with the pi-phase shift and Fano resonance forming in them.
Keywords:fiber optic refractometer of parallel type, Bragg grating with phase pi-shift, measurement of tensile/compression deformation, ring Bragg grating with phase pi-shift, resolution, Fano resonance.
