Ion traps are a promising platform for realizing high-performance quantum computers and atomic clocks. To make these systems scalable, integrated photonic components for guiding and manipulating laser light on a chip scale are important. We will report on finite element simulations of our integrated ion traps. In the simulations, we examined the distortion of the potential at the position of the ion due to the openings in the electrodes for the outcouplers. Our simulations indicate that a transparent conductive coating can help to smoothen the potential. Further, we study how our traps can benefit from grating outcouplers designed with shallow angles.
