Abstract
The refractive index (RI) characterization of fiber Bragg gratings (FBGs) is crucial in monitoring and validating these fabricated structures. Quantitative phase imaging (QPI) is a uniquely promising candidate to accomplish refractive index characterization with the simultaneous benefits of noninvasive technique, sub-micron resolution, and quantitative 3D recovery of refractive index. Approaches are presented to overcome challenges that have previously acted as major obstacles in this field of research. A form of tomographic deconvolution phase microscopy (TDPM) is used to experimentally demonstrate the characterization abilities QPI can provide for various classes of FBGs.
