Anti-resonant hollow-core fibers are optical fiber waveguides which exhibit very low dispersion, high damage threshold and ultra-low nonlinear response. However, they typically deliver the light in several spatial modes, whereas their application usually requires that they support a single spatial mode. We report the principles, fabrication, demonstration and characterization of anti-resonant hollow-core fibres with strong differential modal attenuations and low overall attenuations. These fibers perform as single-mode and are eminently suitable for delivery of powerful ultrashort optical pulses in machining, cutting, welding and multiphoton microscopy applications.
反谐振空芯光纤是一种光纤波导，具有极低的色散、高损伤阈值和超低的非线性响应。然而，它们通常以多种空间模式传输光，而其应用通常要求它们支持单空间模式。我们报告了具有强差分模式衰减和低总衰减的反谐振空芯光纤的原理、制造、演示和表征。这些光纤表现为单模，非常适合在加工、切割、焊接和多光子显微镜应用中传输强大的超短光脉冲。
