- Abstract
This paper discusses the performance of different tapered structures of MMI Couplers. This research studies the effect on MMI coupler performance by varying MMI width, MMI length and also tapering the input/output waveguide. The performance was measured by observing the output power ratio and insertion loss (IL). The linear, parabolic, exponential, symmetrical and non-tapered MMI coupler were modelled using Finite difference beam propagating method (BPM). Each model was simulated in the OptiBPM simulator 2D to illustrate the optical field propagation. Furthermore, the output power and insertion loss were measured in OptiBPM Analyzer. Parabolic tapered with a width of 26 μm has produced the lowest insertion loss of 0.27 dB. On the other hand, the non-tapered MMI coupler has the worst performance of 1.67 dB. A minimum length of 278 m can be used to build the symmetrical tapered MMI coupler, which also turns out to be the most compact one. This study showed that the device's low insertion loss and small size have highlighted its potential for use in photonics applications.
