    Abstract: In general, in one aspect, the invention features an apparatus that includes a photonic crystal fiber (200, 900) configured to guide a mode of electromagnetic radiation at a wavelength, λ, along a waveguide axis. The fiber includes a core (210) extending along the waveguide axis, and a confinement region (220, 910) extending along the waveguide axis and surrounding the core (210). The confinement region (220, 910) includes alternating layers (211-219, 920-922) of a first and a second dielectric material having thicknesses d 1 and d 2 and different refractive indices n 1 and n 2 , respectively. The thickness of at least one of the alternating layers of the first material differs from thickness d 1 QW or at least one of the alternating layers of the second material differs from thickness d 2 QW , where d 1 QW and d 2 QW correspond to a quarter-wave condition for the two dielectric materials given by Formula (I) and Formula (II), respectively. The photonic crystal fiber has an attenuation for the guided mode at the wavelength λ that is reduced by a factor of about two or more relative to an attenuation for a reference fiber that is identical to the photonic crystal fiber except that the reference fiber has alternating layer thicknesses corresponding to the quarter-wave condition.

    Abstract translation: 通常，在一个方面，本发明的特征在于一种装置，其包括被配置成沿着波导轴引导波长λ的电磁辐射模式的光子晶体光纤（200,900）。 光纤包括沿着波导轴线延伸的芯部（210）和沿波导轴线延伸并围绕芯部（210）的约束区域（220,910）。 限制区域（220,910）包括分别具有厚度d1和d2以及不同折射率n1和n2的第一和第二电介质材料的交替层（211-219,920-922）。 第一材料的至少一个交替层的厚度不同于厚度d1 ，或者第二材料的至少一个交替层与厚度d2 不同，其中d1 和d2 对应于分别由式（I）和式（II）给出的两种电介质材料的四分之一波长条件。 光子晶体光纤对于在波长λ处的导模的衰减相对于与光子晶体光纤相同的参考光纤的衰减相比减小约两倍或更多的因子，除了参考光纤具有交替层 厚度对应于四分之一波长条件。
