    • A microstructured optical waveguide is formed to include a periodic sequence of “plugs” of optically active material within the inner cladding air tunnels. The plugs are utilized as a grating structure for generating resonant and periodic structures. The waveguide (in one embodiment, an optical fiber) is tunable by changing the spacing of the plugs (e.g., heating the structure, changing the pressure within the structure, etc.), or by modifying the initial spacing of the plugs during the formation of the microstructured optical waveguide (i.e., by modifying the “dipping frequency” of the waveguide into a reservoir of optically active material). In general, any number of different types of optically active material may be used to form the plugs, where two or more different materials may be used in the same structure, and introduced in an alternating fashion.
    • 形成微结构化光波导以在内包层空气隧道内包括光学活性材料的“插塞”的周期性序列。 插头被用作用于产生谐振和周期性结构的光栅结构。 波导(在一个实施例中,光纤)可通过改变插头的间距(例如,加热结构,改变结构内的压力等)来调节,或通过在形成期间修改塞子的初始间隔来调节 的微结构光波导(即,通过将波导的“浸渍频率”改变为光学活性材料的储存器)。 通常,可以使用任何数量的不同类型的光学活性材料来形成插塞,其中可以以相同的结构使用两种或更多种不同的材料,并以交替方式引入。
