We report, for the first time to our knowledge, achievement of all-fiber distributed Gires–Tournois etalons (DGTEs) based on fiber Bragg gratings. DGTEs with both separated structure and overlapped structure were investigated. Such grating-based DGTEs show periodic spectral characteristics that are similar to those of conventional Gires–Tournois etalons; however, they also have some particular characteristics that are due to the dispersive nature of the gratings.
