Intrinsic phase response retrieval of notch in reflection spectrum of a phase-shifted fiber Bragg grating based on magnitude response measurement

An approach to retrieving intrinsic phase response of optical filters from magnitude response only measurement is proposed and demonstrated. Phase retrieval is based on the fact that the intrinsic phase response of an optical filter with a minimum phase response has a unique relationship with its magnitude response. A phase retrieval algorithm based on fast Fourier transform is proposed. In the experiment, the intrinsic phase response of notch in the reflection spectrum of a phase-shifted fiber Bragg grating is successfully retrieved from the measured magnitude response, which is free of the influence of fiber pigtail in the measurement setup.
