There is a burgeoning transformation in the optics & photonics world driven by old and new applications that benefit from a beam of light with the shape of an annular ring. Current methods of generating and delivering such annular beams mostly rely on a complex arrangement of maintenance-intensive and bulky optical components that inhibits industrial adoption. To address this issue, a novel type of optical fiber called "annular-core photonic crystal fiber" (AC-PCF) has been developed. The AC-PCF allows the efficient generation and delivery of singularly annular beams at all input wavelengths - a unique feature - in a simple, flexible, compact and cost-effective manner. The AC-PCF is thus uniquely tailored to deliver high-quality annular beams over a very wide bandwidth and for a variety of applications. In this project, we focus on three rapidly growing segments of the optics & photonics industry that can immediately benefit from the AC-PCF: laser material processing, light beam shaping and super-resolution microscopy. With the collaboration of three leading photonic industrials, we propose in this project to fabricate, test and validate the commercial potential of this fiber-optic technology within fiber-laser material processing and high-resolution fiber-optic microscopy scenarios, in particular. A commercialization strategy is also outlined for the intellectual protection of the technology and its eventual transfer to potential industrial end-users.

在受益于环形光束的新旧应用的推动下，光学和光子学领域正在发生一场蓬勃发展的变革。目前产生和传输此类环形光束的方法主要依赖于维护密集型且笨重的光学元件的复杂布置，这阻碍了工业采用。为了解决这个问题，一种新型光纤被称为“环芯光子晶体光纤”（AC-PCF）。 AC-PCF 能够以简单、灵活、紧凑且经济高效的方式在所有输入波长上高效生成和传输奇异环形光束，这是一项独特的功能。因此，AC-PCF 经过专门定制，可在非常宽的带宽上为各种应用提供高质量的环形光束。在这个项目中，我们重点关注光学和光子行业中可以立即受益于 AC-PCF 的三个快速增长的领域：激光材料加工、光束整形和超分辨率显微镜。通过与三个领先的光子工业公司的合作，我们建议在这个项目中制造、测试和验证这种光纤技术在光纤激光材料加工和高分辨率光纤显微镜场景中的商业潜力。还概述了商业化战略，以保护该技术的知识产权及其最终转移给潜在的工业最终用户。
