Most splitters used in optical network such as a directional coupler can divide power into two or more outputs, but it is technically hard to fabricate due to its wavelength independence and its strict length requirements. One of the solutions of this strict fabrication tolerance is by introducing a large core in the splitting region as to accommodate more modes and splitting outputs. In this paper we design 1 × 16 MMI coupler, with optimum parameters to make the size of the device is practically still small. Power splitting ratio can be achieved at some special position where the mode front has 16 powers splitting level. We have used the Methods of Line to solve Helmholtz Equation in MMI structures. Further absorbing boundary condition is also used to prevent back reflection from the edge of calculation windows so that the error in calculation can be minimized. The calculation shows that MMI couplers have better tolerance on wavelength variation compare to standard type of directional couplers.
