In this project, we are taking advantage of the superior optical and chemical properties of tellurite glasses to produce microstructured fibers using extrusion. Extrusion is a very versatile technique for the fabrication of fibers composed of soft glasses, i.e. with low melting temperatures. It will facilitate a relatively easy exploration of several different optical microstructure design simply by changing the die. The nonlinear optical properties of several new optical microstructures (nonlinear index, stimulated Raman scattering and Four Wave Mixing) will be characterized. The outcome of the work will be the determination of the key features that provide a tight confinement of the light, (for highest optical densities and higher nonlinearities) and a flat dispersion (necessary for phase matching in nonlinear optical processes). In this project, we are exploring a new method to fabricate novel optical fibers with extrusion. Because of their microstructure, these fibers possess unique (nonlinear) optical properties that can be used in applications ranging from medical imaging to optical communications. Extrusion is a well known technique for the forming of metals which will be applied to soft glasses for the fabrication of these novel fibers.

在这个项目中，我们利用亚碲酸盐玻璃优异的光学和化学特性，通过挤出生产微结构纤维。 挤出是一种非常通用的技术，用于制造由软玻璃组成的纤维，即具有低熔化温度。只需更换模具，即可相对轻松地探索几种不同的光学微结构设计。 将表征几种新型光学微结构（非线性折射率、受激拉曼散射和四波混合）的非线性光学特性。 这项工作的结果将是确定提供光的严格限制（用于最高光密度和更高的非线性）和平坦色散（非线性光学过程中的相位匹配所必需的）的关键特征。 在这个项目中，我们正在探索一种通过挤压制造新型光纤的新方法。 由于其微观结构，这些光纤具有独特的（非线性）光学特性，可用于从医学成像到光通信的各种应用。 挤压是一种众所周知的金属成型技术，该技术将应用于软玻璃来制造这些新型纤维。
