Optical Microstructures Fabricated with Direct Laser Writing Technique

Open access


Three-dimensional photolitography, also known as Direct Laser Writing (DLW), is a powerful technique for fabrication of photonic microstructures. In this paper we present the basics of the relevant technology and discuss some features of the fabrication process. We also describe the experimental setup designed for making colour filters based on diffraction gratings, fibre-tip-integrated lens and anti-reflective coating designed for telecom wavelength (1550 nm). The results obtained demonstrate the DLW technique to be a promising fast prototyping fabrication method that may allow manipulating the properties of optical materials.
