Comparison of Optical Properties of 1x8 Splitters Based on Y-Branch and MMI Approaches

Popis výsledku v původním jazyce

1x8 Y-branch and MMI splitters were designed, simulated and the obtained results of both approaches were studies and compared with each other for such splitters. The core size of the used waveguides is usually 6 x 6 µm2 to match the diameter of the single mode input/output fibers, i.e. to keep the coupling loses as low as possible. In this work we show that the used waveguide core size supports not only propagation of the single mode but of the first mode too, leading to an asymmetric splitting ratio (increasing non-uniformity of the split power over all the output waveguides). Decreasing waveguide core size it is possible to suppress presence of the first mode and this way to reduce non-uniformity, nearly to one half of the original value.
