title: Pixelated high-index ring Bragg fibers.
abstract: A new type of Anti Resonant Reflecting Optical Waveguide (ARROW) fiber with a low refractive index contrast is reported. This waveguide is similar to a Bragg fiber for which the high index rings are replaced by discontinuous rings made of circular High Index Inclusions (HII). As compared to conventional Bragg fibers, such a new structure enables true Photonic BandGap (PBG) guidance and limits the number of cladding modes located within the high index regions, thus enhancing the guiding properties. A Mode Field Diameter (MFD) of 26 μm is reported at a wavelength of 1400 nm. Single Mode (SM) behavior is also observed beyond 1400 nm for a 1 m-long fiber.
