In this paper we describe the direct laser writing of complex structures in a multifunctional acrylate polymer system using fan-out and grey-scale diffractive optical elements (DOE). The effective writing speed of waveguides was successfully increased using a fan-out DOE element. The DOEs to produce greyscale outputs (such as an intensity ramp) and other complex outputs (such as Heriot-Watt University logo) were used to fabricate greysclae and complex structures in polymer. Quantitative fabrication results of these structures are presented in this paper.
