Trapped-ion quantum computers are based on ions as quantum systems to realize the qubits. In these systems, certain trapped ions are controlled and manipulated by laser light of multiple wavelengths ranging from the near-ultraviolet to the near-infrared spectral range. Integrated photonic elements like waveguides and couplers are required for scalable compact chip-based trapped-ion quantum computers. State-of-the-art research solutions utilize multiple waveguides and couplers to address individual wavelengths. Thus, each ion must be controlled by multiple waveguides and couplers. This sets a limit to the realization of compact systems in the long-term view. To minimize the size of a single ion trap chip, photonic devices for multi-wavelength operation are necessary. In this contribution, we show and discuss optical simulations of the broadband performance for single mode integrated optical buried channel waveguides. Furthermore, we present approaches for broadband waveguide designs to achieve the desired goal of multi-wavelength single mode operation.
