One of the main obstacles to the scalability of ion trap applications such as quantum computing and quantum sensing is the miniaturization and scalability of the optics required to provide the trapped ions with the light necessary to manipulate them. In this talk, we will present a surface ion trap with integrated optics that requires much less space than classical setups. Integrated optics also offer routes to eliminating important technical noise sources present in conventional setups. The integrated optics deliver all the lasers required for a Yb 172 clock experiment to the ion. One of the main features of the trap is a grating coupler that provides the ion with light in a Hermite-Gaussian mode to excite the narrow Yb 172 octupole transition.
