Discrimination of bending and temperature sensitivities with phase-shifted long-period fiber gratings depending on initial coupling strength.
The discrimination of bending and temperature sensitivities based on phase-shifted long-period fiber gratings is discussed. Their spectral evolution during phase-shifted grating formation by UV post-exposure corresponding to their initial coupling strength is also presented.
