Photonic integrated circuits (PICs) for on-chip light manipulation can be employed in scalable chip-based trapped-ion quantum computers. Trapped ions are used as qubits and are controlled by multiple wavelengths ranging from the near-ultraviolet (NUV) up to the near-infrared (NIR). The design of UV-PICs is a challenging task, since smaller dimensions and higher propagation losses are inevitable. This contribution covers the design of single-mode integrated optical waveguides on different material platforms for selected NUV and VIS wavelengths of an Yb+ ion. To improve the scalability, multi-wavelength operation is investigated.
