title: Dual-direction Gires-Tournois etalon based on a single complex fiber Bragg grating.
abstract: We propose and demonstrate a single fiber Bragg grating-based Gires-Tournois (GT) etalon, which is realized by applying a complex apodization profile on a linearly chirped fiber Bragg grating. Such a GT etalon not only has a simplified fabrication procedure but also can operate in dual directions.
