We demonstrate a broadband 1×3 power splitter based on inverse design, with a compact footprint of 2.8 × 2.8μm2, and a power ratio of 25%:50%:25% at 1550nm. The ...

To achieve intra-chip three-dimensional (3-D) integration of silicon photonic circuits, we design a polarization beam splitter based on complementary metal-oxide-semiconductor (CMOS) platform. With ...
