The slab gaussian beam is set up to focus at a distance of 25 um away from the source position.Ī parameter sweep project has been set up to track the transmission into the output waveguide as a function of the exponent m. The file taper_design.lms contains a 2.5D propagator simulation region with a slab gaussian beam as the source. \(m=2\) corresponds to a parabolic shaped taper. \(m=0.5\) corresponds to a square root shaped taper. At the two ends of the taper, we are constrained to the waveguide width of \(w_1\) and \(w_2\). The taper design in this case will be proportional to \(x\) to the power of exponent \(m\). We will start by parameterizing the design of this taper as follows: ] that this taper can be simulated using the eigenmode expansion (EME) solver as well. In this example, we will determine the optimal shape of an SOI taper using MODE 2.5D variational FDTD solver. ![]()
