Novel photonic structures, such as photonic crystals and metamaterials, are causing a revolution in the way in which we think about controlling, manipulating and using light. Such materials can be manufactured using 3D structuring on the sub-micron/nanometre scale. Most conventional methods of fabrication on this scale are two-dimensional, so are not suited for the efficient construction of 3D materials. However, using non-linear laser-induced optical processes one can create structures with sub-micron 3D resolution as the fabrication effects are confined to the laser focus, rather than being spread out along the beam. There are however limitations that obstruct the further development of such techniques into a viable industrial process. One issue is the loss of resolution and effectiveness of fabrication as one focuses deeper into a 3D material - this limits the currently achievable device thickness. Another limitation is speed - existing processes are often slow, being constrained by the optical design of the systems to serial point-by-point fabrication. In this project, we will develop and apply active and adaptive optical techniques, based around deformable mirror and liquid crystal devices, to overcome these limitations and make 3D optical processing more effective as a manufacturing technology.

新的光子结构，如光子晶体和超材料，正在引起我们思考控制，操纵和使用光的方式的革命。这种材料可以使用亚微米/纳米尺度的3D结构来制造。这种规模的大多数传统制造方法都是二维的，因此不适合3D材料的有效构建。然而，使用非线性激光诱导光学工艺，可以创建具有亚微米3D分辨率的结构，因为制造效果被限制在激光焦点，而不是沿着光束沿着展开。然而，存在阻碍将此类技术进一步发展为可行的工业过程的限制。一个问题是当人们更深入地聚焦到3D材料中时，制造的分辨率和有效性的损失-这限制了当前可实现的器件厚度。另一个限制是速度-现有的工艺通常很慢，受到系统的光学设计的限制，只能进行连续的逐点制造。在这个项目中，我们将开发和应用基于可变形镜和液晶器件的主动和自适应光学技术，以克服这些限制，并使3D光学处理作为一种制造技术更有效。
