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 ...

We demonstrate two kinds of low-loss 1 × 4 optical power splitters based on multimode interference (MMI) couplers. By using the adjoint shape optimization method, the shapes of MMI couples are ...
