报告摘要：

Microstructured optical fibers (MOFs), or photonic crystal fibers (PCFs), made from fused silica have been intensively investigated during the last two decades, and have been proven highly successful in many research fields of fiber optics. Fused silica, however, suffers from strong material absorption in the mid-IR (above 2 μm), as well as ultraviolet-induced optical damage (solarization), which limits performance and lifetime in the ultraviolet (<380 nm). Silica-based fibers are therefore restricted to applications within the above spectral limits. MOFs made from soft glasses (e.g., heavy-metal oxide, fluoride or chalcogenide) have attracted much interest because of extended ultraviolet (UV) and mid-infrared (mid-IR) transmission windows, higher Kerr nonlinearities and refractive indices and increased rare-earth solubility.

 The talk will be focused on advanced soft-glass fiber drawing techniques that have been developed over the last few years, examples being 3D printing of complex extrusion dies, advanced differential etching procedures, and techniques for producing chirally twisted fibers. Then it will move on to discuss a range of novel applications, such as supercontinuum generation, opto-mechanical devices, imaging through multimode fibres, photochemistry and nonlinear wavelength conversion.
