Two novel kinds of anti-resonant polygonal-core hollow fibers are introduced to work at near- and middle-infrared wavelengths, including a triangular-core fiber-design with surrounding silica-glass webs, and a negatively curved square-core fiber-design. By mechanism of anti-resonance, these fibers can guide light with low losses over a wide wavelength range, as well as significant compression of high-order modes and group velocity dispersion.
