Guiding 2.94 μm using low-loss microstructured antiresonant triangular-core fibers

الأصل · EN

We introduce a new simple design of hollow-core microstructured fiber targeted to guide mid-infrared light at a wavelength 2.94 μm. The fiber has a triangular-core supported via silica-glass webs enclosed by a large hollow capillary tube. The fiber specific dimensions are determined based on the guiding technique, which is based on the anti-resonant mechanism. For a triangular-core with side length 100 μm, the fiber has a minimum transmission loss 0.08±0.005 dB/m and dispersion 2.3 ps/km/nm at the operational wavelength 2.94 μm.
