The PLASMOCOM project proposes a Y-splitter design that introduces a 520 nm gap in the left arm of the Y-splitter at the branching point. The branches measure 7 µm in length, with a separation of 3 µm between the output arms. By changing the shape of the region where the two output waveguides emerge from the splitting region, the scattering losses are reduced. Image Credit: Antoly Zayats |
