项目摘要

Silicon photonics is one of the largest and fastest growing areas of research and development of our time. The ability to exploit the semiconductor functionality to process and transmit data in the form of light offers a route to dramatically increase the speeds, capacities, and efficiencies of next generation optoelectronic systems. An important subset of this work is nonlinear silicon photonics, where the aim is to make use of the large, ultrafast, nonlinearity of the material to intricately control and manipulate these light-based signals using light itself. Nonlinear processes in silicon have been widely studied, with significant device demonstrators including Raman lasers, parametric amplifiers, and high-speed modulators. However, most of these devices have been constructed from single crystal material platforms that are notoriously difficult to integrate, either with other elements on-chip or with the optical fibres that are used to link the systems together. Thus, if nonlinear silicon devices are to make the critical transition from a research curiosity to commercially viable products, these integration hurdles must be overcome.The work in this fellowship application will develop procedures to directly incorporate nonlinear optical components fabricated from cheap and easy to deposit materials within highly functional photonic systems. Compared to their single crystal counterparts, these materials offer a number of key advantages as they are compatible with a wide range of substrates, can be shaped in three dimensions, and can even be post-processed to fine-tune the optical properties and/or the waveguide structure. The components will be fabricated in both fibre and planar form, thus opening an innovative route towards linking these two platforms - one of the most important design challenges in the field of silicon photonics. Following optimization of the integration methods and materials, a range of nonlinear optical systems will be constructed, with the goal to obtaining systems that are smaller, faster, and more efficient. Although the primary focus of this project is the development of integrated platforms for optical communication systems, by extending the device operation into the mid-infrared wavelength region there will be scope to target applications in important areas such as environmental sensing, healthcare, and public security. By looking beyond the traditional single crystal chip-based components to consider more flexible materials and geometries, the work in this programme will help bring the vision of truly integrated nonlinear silicon platforms to fruition.

硅光子学是我们这个时代规模最大、发展最快的研发领域之一。利用半导体功能以光的形式处理和传输数据的能力提供了一条显著提高下一代光电子系统的速度、容量和效率的途径。这项工作的一个重要子集是非线性硅光子学，其目的是利用材料的巨大、超快、非线性来利用光本身来复杂地控制和操纵这些基于光的信号。硅中的非线性过程已经得到了广泛的研究，重要的器件演示包括拉曼激光器、参数放大器和高速调制器。然而，这些设备中的大多数都是由单晶材料平台构建的，众所周知，这些平台很难与芯片上的其他元件或用于将系统连接在一起的光纤集成。因此，如果非线性硅器件要实现从研究的好奇心到商业上可行的产品的关键转变，这些集成障碍必须被克服。这项奖学金申请中的工作将开发程序，直接将由廉价且易于沉积的材料制造的非线性光学元件集成到高功能光子系统中。与单晶材料相比，这些材料提供了许多关键优势，因为它们与广泛的衬底兼容，可以三维成形，甚至可以进行后处理以微调光学特性和/或波导结构。这些组件将以光纤和平面的形式制造，从而为连接这两个平台开辟了一条创新的道路-这是硅光电子领域最重要的设计挑战之一。随着集成方法和材料的优化，将构建一系列非线性光学系统，目标是获得更小、更快和更高效的系统。虽然该项目的主要重点是开发光通信系统的集成平台，但通过将设备操作扩展到中红外波长区域，将有机会针对环境传感、医疗保健和公共安全等重要领域的应用。通过超越传统的基于单晶芯片的元件，考虑更灵活的材料和几何结构，该计划的工作将有助于实现真正集成的非线性硅平台的愿景。
