We describe the application of beam shaping for the creation of multiple foci and their use in femtosecond laser writing. This technique is capable of producing waveguide based photonic devices in a single sweep by simultaneously writing. We give an introduction into the beam shaping algorithm and show results of sample devices (e.g. couplers) with their guiding properties and their specific functional properties.
