Abstract
In this paper, different single-mode Y-branch splitters are simulated based on symmetric Y-branch comprising different waveguides (straight, S-Bend Cosine, S-Bend Sine and S-Bend Arc waveguides) with a channel profile of proton-exchanged lithium niobate. Apart from the waveguides length of the two branches, all other parameters such as the width of the waveguides and separation of the two branches are considered fixed. The distance between the two output waveguides is 127μm (center-to-center), which is suitable for the connection with the fibers. For each structure, the excess loss of the splitter is checked, and according to the minimum loss, optimum length of waveguide is determined. Finally, an optimum single-mode Y-branch splitter is selected..
