项目摘要

This project will significantly advance practical optoelectronic-integrated-circuits (OEICs) with a suite of examples relevant to a major high-tech manufacturing company. The first circuit will use chromatic confocal profilometry, which is an established technique for measuring the shape of industrial parts and, where the part is transparent, its thickness. Systems commonly comprise a fibre-coupled broadband light source, a fibre splitter and a spectrometer all in a remote, control box, and an objective lens with axial chromatic dispersion at the point of measurement. Creating an equivalent chip based system will enable applications such as in-situ, on co-ordinate measuring machines, due to the size and weight advantages and the removal of the need for fibre routed through the machine. We will investigate novel schemes for integrating all the individual components into a photonic integrated circuit. The work will require the development of efficient, matched, emitters and detectors, the use of waveguides and, depending on the scheme or schemes investigated in hardware, spectrometers, modulators, analogue circuits, all integrated on a single chip. The successful outcome from the research will result in a novel, disruptive, technology for chromatic confocal profilometry with potential application to many areas of spectral measurement. Further ground breaking systems should follow.

该项目将通过一系列与一家大型高科技制造公司相关的例子，大大推进实用的光电子集成电路（OEIC）。第一个电路将使用彩色共焦轮廓术，这是一种用于测量工业零件形状的成熟技术，如果零件是透明的，则测量其厚度。系统通常包括光纤耦合宽带光源、光纤分路器和光谱仪，所有这些都在远程控制盒中，以及在测量点处具有轴向色散的物镜透镜。创建一个等效的基于芯片的系统将使应用程序，如在现场，坐标测量机，由于尺寸和重量的优势，并消除了需要通过机器路由的光纤。我们将研究新的方案，将所有的单独组件集成到一个光子集成电路。这项工作将需要开发高效、匹配的发射器和检测器，使用波导，并根据硬件、光谱仪、调制器、模拟电路中研究的一种或多种方案，将所有这些都集成在一个芯片上。这项研究的成功结果将为彩色共焦轮廓术带来一种新颖的、颠覆性的技术，并可能应用于光谱测量的许多领域。应该会有更多的突破性系统。
