The development of robust infrared fibers is crucial for harnessing the capabilities of new mid-infrared lasers. We present a novel approach to the fabrication of chalcogenide glass fiber preforms: one-step multimaterial extrusion. The preform consists of a glass core and cladding surrounded by a built-in, thermally compatible, polymer jacket for mechanical support. Using this approach we extrude several preform structures and draw them into robust composite fibers. Furthermore, the polymer cladding allows us to produce robust tapers with submicrometer core diameter.
开发坚固的红外光纤对于利用新型中红外激光器的功能至关重要。我们提出了一种制造硫属玻璃光纤预制棒的新方法：一步多材料挤压法。预制棒由玻璃芯和包层组成，周围是内置的、热兼容的聚合物护套，用于机械支撑。使用这种方法，我们可以挤出几种预制棒结构，并将其拉制成坚固的复合纤维。此外，聚合物包层使我们能够生产具有亚微米芯径的坚固锥形件。
