The proposal requests a 3-D translation stage to facilitate investigation of 3-D writing of refractive index structures beneath the surface of un-doped poly (methyl methacrylate) (PMMA) using tuneable femtosecond (fs) laser irradiation. The aim is to: (1) Minimise feature size by using holographic optics; minimising the writing wavelength used (down to 240nm). (2) Maximise the refractive index modulation by appropriate choice of writing wavelength (240-1200nm) and velocity, laser fluence and number of overwrites. (3) Investigate photochemistry using analytical techniques.(4) Explore two-photon stereolithography for direct and indirect fabrication of polymer microstructures. The proposal is multidisciplinary; exploiting expertise in optical waveguide/fibre instrumentation, polymer and analytical chemistry at the University of Manchester, access to a femtosecond laser and a PhD studentship supplied by Unilever (Port Sunlight) and a femtosecond loan pool laser supplied by Rutherford Appleton Laser Loan Pool Facility.

该提案要求使用可调谐飞秒（fs）激光照射，在未掺杂的聚甲基丙烯酸甲酯（PMMA）表面下进行折射率结构的三维书写研究。目标是：(1)通过使用全息光学最小化特征尺寸；尽量减少使用的写入波长（低至240nm）。(2)通过适当选择写入波长（240-1200nm）、速度、激光通量和覆盖次数，最大限度地提高折射率调制。(3)利用分析技术研究光化学。(4)探索双光子立体光刻直接和间接制备聚合物微结构的方法。这个建议是多学科的；利用曼彻斯特大学在光波导/光纤仪器、聚合物和分析化学方面的专业知识，获得联合利华（Port Sunlight）提供的飞秒激光器和博士学位，以及卢瑟福阿普尔顿激光贷款池设施提供的飞秒激光器。
