Abstract: Hollow-core Bragg fibers (HC-BFs) based on the one-dimensional photonic bandgap (PBG) effect have attracted increasing attention in recent years, because of their ability to flexibly and conveniently regulate the PBG structure, as well as their excellent performance in broadband and low-loss transmission. As a distinctive category of hollow-core PBG fiber, HC-BFs show great potential in lightwave transmission, dispersion management and tailoring, fiber-type devices, sensing and so on. The development and recent research progress of HC-BFs are reviewed, with regard to the structural design and modal properties, cladding materials and fabrication technologies, and their applications in trace-gas detection and biochemical sensing based on gaseous or liquid analyte-filled HC-BFs.
