The realization of an all-solid microstructured optical fiber based on chalcogenide glasses was achieved. The fiber presents As(2)S(3) inclusions selected as low refractive index material (n = 2.4) embedded in a As(38)Se(62) glass matrix (n = 2.8). The single mode regime of the fiber was demonstrated both theoretically by multipole method calculations and experimentally by near field measurements. Optical transmission measurements of the microstructured fiber and single index fibers made of the initial glasses reveal an excess of losses as high as 6-7 dB/m. This excess is not due to the guide geometry but can be explained by the presence of defects in the glass interface regions.
实现了基于硫系玻璃的全固态微结构光纤。该光纤呈现出作为低折射率材料（n = 2.4）的As₂S₃夹杂物，其嵌入在As₃₈Se₆₂玻璃基质（n = 2.8）中。通过多极方法计算从理论上证明了该光纤的单模状态，并通过近场测量从实验上进行了证明。对微结构光纤和由初始玻璃制成的单折射率光纤的光传输测量表明，存在高达6 - 7 dB/m的额外损耗。这种额外损耗并非由于波导几何结构引起，而是可以由玻璃界面区域中缺陷的存在来解释。
