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.
We propose and demonstrate a novel optically tunable dynamic dispersion-compensation device with coupled-cavity etalon structure. Experimentally, it was achieved with an all-fiber coupled-cavity etalon made in an Er/Yb codoped fiber pumped by a 980-nm laser diode. The dispersion was tuned from -300 to +400 ps/nm in the experiment. The potential advantages of such optically tunable dispersion compensators include fast response time and remotely controllable operation.
We present a novel concept of a tailored Gires-Tournois etalon structure and show that such a device is useful for the fabrication of a dispersion-slope compensator with an almost arbitrary dispersion profile and also with tunability in the dispersion slope.
We report for what is believed to be the first time the use of transmissive fiber Bragg grating-based Fabry-Perot etalons for tunable dispersion compensation and dispersion-slope compensation. The resulting device has a number of advantages, such as low cost, ease of fabrication, full optical fiber compatibility, and simplicity.
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.
