项目摘要

The age of optical communications has been enabled by two key materials and technological breakthroughs: low loss silica optical fibre waveguides and silicon based electronics. In order to integrate these two technologies, one of which is fibre based and the other planar chip based, the devices have to be interfaced via complex intermediate optics. Clearly the ability to combine the flexible light guiding capabilities of glass fibres with the rich optoelectronic functionality of silicon in an integrated fibre geometry is an exciting prospect. For example, we could then consider building lasers, modulators, switches, detectors and even electronic circuits all inside a compact fibre geometry. This proposal describes research that will follow the development of silicon impregnated optical fibres from the design and characterization stage, to the demonstration of practical all-fibre devices. The fabrication of these hybrid structures will utilize the unique framework of microstructured optical fibres, which contain microscale air holes that run down their length, as 3D templates into which the semiconductor material will be deposited. The proposed structures will form the basis of a number of devices including in-fibre semiconductor lasers, high speed all-optical modulators, broadband sources that extend into the mid-infrared and tuneable photonic band gap fibres (PGBFs). Fiberized silicon devices offer significant advantages such as low cost, versatility, robust waveguide geometries, compactness and highly extended electromagnetic interaction lengths. Importantly, the potential applications of this work extend far beyond the optical telecommunications field to include a wide range of disciplines such as medicine, spectroscopy and security monitoring, ensuring a high level of both scientific and commercial relevance.

光通信时代的到来，得益于两大关键材料和技术的突破：低损耗石英光纤波导和硅基电子器件。为了集成这两种技术，其中一种是基于光纤的，另一种是基于平面芯片的，这些设备必须通过复杂的中间光学器件进行接口。显然，在集成纤维几何结构中将玻璃纤维的柔性光导能力与硅的丰富光电功能性联合收割机结合的能力是令人兴奋的前景。例如，我们可以考虑在紧凑的光纤几何结构中构建激光器、调制器、开关、检测器甚至电子电路。该提案描述了从设计和表征阶段到实际全光纤设备演示的硅浸渍光纤开发的研究。这些混合结构的制造将利用微结构光纤的独特框架，其包含沿其长度延伸的微米级气孔，作为半导体材料将沉积到其中的3D模板。拟议的结构将形成许多设备的基础，包括光纤半导体激光器，高速全光调制器，延伸到中红外和可调谐光子带隙光纤（PGB F）的宽带源。纤维化硅器件提供了显著的优点，例如低成本、多功能性、稳健的波导几何形状、紧凑性和高度延伸的电磁相互作用长度。重要的是，这项工作的潜在应用远远超出了光通信领域，包括医学、光谱学和安全监测等广泛学科，确保了高水平的科学和商业相关性。
