Comparison of Optical Properties of 1 x 8 Splitters Based on Y-Branch and MMI Approaches

Popis výsledku v původním jazyce

1 x 8 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 ?m2 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.
