Using the full phase compensation method, we derive a set of precise phase compensation formulas to design a three-dimensional microprism-type Y junction. The simulated and traditional results are compared to verify that the proposed structure is better. By taking into account the orthogonality principle to estimate the branching losses, the proposed structure was improved to better than approximately 6–10% over the traditional structure.
