We propose a simple
design of 1×3 optical power splitter which
uses gallium nitride (GaN) on sapphire. The design consists of widely used large cross section input rib
waveguide, a rectangular multimode interference (MMI) structure, and three-branch rib waveguides. The MMI
structure is selected since
their attractive performances, such as compactness, low excess loss, wide bandwidth and ease to fabricate. The power splitter is designed for the third telecommunication window,
i.e., l = 1.55 µm. Optimization
of the geometrical structure parameters for the design is conducted theoretically utilizing 3D FD-BPM method. It is found that the power splitter exhibits excess loss
of 0.46 dB and imbalanced of 0.001 dB at l = 1.55 µm for
