TL;DR: In this article, the authors reported the calculation and fabrication of periodic phase structures for fan-out elements with a theoretical conversion efficiency close to 100% and perfect uniformity, and measured an efficiency of 92% for a smooth kinoform structure fabricated in photoresist by laser beam writing lithography.
Abstract: This paper reports the calculation and fabrication of periodic phase structures for fan-out elements with a theoretical conversion efficiency close to 100% and perfect uniformity. We have measured an efficiency of 92% for a smooth kinoform structure fabricated in photoresist by laser beam writing lithography.

TL;DR: This is the first demonstration of three-photon polymerization, a process that may allow the fabrication of components of very high resolution, by polymerizing ORMOCER with an ultrafast laser irradiation at 1028 nm.
Abstract: We report the fabrication of three-dimensional structures of submicrometer resolution by three-photon polymerization. This resolution has been achieved by polymerizing ORMOCER, a UV photocurable organic–inorganic hybrid material, with an ultrafast laser irradiation at 1028?nm. To our knowledge, this is the first demonstration of three-photon polymerization, a process that may allow the fabrication of components of very high resolution.

TL;DR: In this article, various all-liquid fabrication strategies to construct polymer micro-lens arrays on glass substrates are presented, and three different variations of the selective wetting process are developed.
Abstract: Various all-liquid fabrication strategies to construct polymer micro-lens arrays on glass substrates are presented. Wettability patterns were made on glass substrates and a monomer was deposited selectively on circular domains on the substrate by making use of the hydrophobic effect, resulting in liquid micro-lenses. The liquid micro-lenses were solidified by polymerization. Three different variations of the selective wetting process were developed. The polymer micro-lenses were characterized extensively by optical methods: focal length, surface roughness and optical aberrations of the lenses were determined by scanning white light interferometry. Due to their fabrication from the liquid phase, the root-mean-square surface roughness of the micro-lenses is between 10 and 35 nm, i.e. better than 1/10 wavelength. These measurements allowed comparison of the quality of lenses fabricated by these techniques.
