The MMI waveguide is represented by the yellow rectangular and it can re-sized (click left)and moved (click right).

Applet parameters :
D1 : waveguide width
nsub : substrate index
W.L. : wavelength
dn1 : waveguide index difference
W : gaussian width of the input field
x0 : position of the gaussian
Length : Length of the computation window
Z : position of the transverse cut profile
