Two dimensional (2D) photonic crystal (PC) slab waveguides are attractive candidate to develop all-optical integrated circuits for future high-speed photonic network system. For developing high-functionality devices, the design of waveguide components is crucial in the PC technology. A topology optimization (TO) method is an efficient optimization algorithm that creates desired material distribution for customizing waveguide components with expected functionality. We employed the TO method to design waveguide components in air-bridge-type, 2D PC slabs. Bu fabricating GaAs-based PC slabs, we successfully demonstrated that the TO design method has remarkably contributed to achievement of intersection, bend, directional coupler and Y-junction waveguides with wide bandwidth and transmittance comparable to that of the straight waveguide. The results are encouraging for the development of a photonic digital processor as well as ultra-fast, all-optical devices based on 2D PC slab waveguides.

二维（2D）光子晶体（PC）平板波导是为未来高速光子网络系统开发全光集成电路的有吸引力的候选者。为了开发高性能设备，波导元件的设计在PC技术中至关重要。拓扑优化 (TO) 方法是一种有效的优化算法，可创建所需的材料分布，以定制具有预期功能的波导组件。我们采用 TO 方法设计空气桥型 2D PC 板中的波导组件。在制造基于GaAs的PC板时，我们成功地证明了TO设计方法对于实现相交、弯曲、定向耦合器和Y结波导具有与直波导相当的宽带宽和透射率做出了显着贡献。这些结果对于光子数字处理器以及基于 2D PC 板条波导的超快全光学器件的开发来说是令人鼓舞的。
