Axial stress profiling for few-mode fiber Bragg grating based on resonant wavelength shifts during etching process
We proposed an analytical model to describe the relationship between the axial stress profile of a few-mode fiber Bragg grating with the variations in the resonant wavelengths during a chemical etching process. As a mechanism of preserving state of equilibrium, the etched fiber is experiencing a var...
