“…The Y-branch waveguide is the fundamental structure of PLC splitters [6]. The abrupt change in the optical mode field at the branching point leads to significant radiation loss [7,8], which is the primary cause of increased device losses and reduced uniformity. Researchers have tackled this issue by introducing structures such as narrow straight waveguides [9], tapered waveguides [10], multimode waveguide transition sections [11], and bent waveguide offset connections [12] to mitigate the loss of Y-branch waveguides.…”

The planar lightwave circuit (PLC) splitter serves as a crucial component in fiber-to-the-home (FTTH). Diverse applications in complex scenarios necessitate a variety of PLC splitters, thereby escalating the complexity of their design. A novel optimization method based on orthogonal experimental design (OED) integrating a backpropagation neural network (BPNN) with a genetic algorithm (GA) is proposed. The optimization results demonstrate that for the 1×8 PLC splitter example, the insertion loss (IL), wavelength-dependent loss (WDL), and uniformity loss (UL) of the designed device are 9.2202 dB, 0.0915 dB, and 0.0914 dB, respectively. Compared to the previous results obtained using a single-parameter optimization method, which yielded an IL, WDL, and UL of 9.5 dB, 0.35 dB, and 0.30 dB respectively, there is a significant performance improvement.
