2. Channel waveguide in SOI platform solved by exact method (Sine). Field distribution in 1D/2D.
Simulated channel waveguide in SOI platform with Exact solution (Sine Basis).
The field distribution of the 1st and 3rd modes are shown in 1D and 2D space. Due to symmetry, only half of the terms are practically in used in each axis.
3. Channel waveguide in non-dispersive platform solved via exact method (Fourier) near cut-off.
Simulated channel waveguide near cutoff conditions (Exact - Fourier). The field distribution of the fundamental mode and its convergence analysis are displayed. 5-digits convergence is achieved.
4. Rib waveguide in SOI platform (Exact w. Sine). Bend waveguide is analyzed for 90° turn.
Simulated rib waveguide and its bend waveguide, or arc (Exact - Sine) with a radius of 2 µm. The bend mode, E1,1(Arc), relating to the 1st mode, E1,1, of the straight waveguide is plotted in 2D. Notice that the field has drifted to the right side due to the curvature shape of the waveguide.
The overall losses of the straight mode, E1,1, due to the waveguide bending, the surface roughness, which is enhanced due to the bending, and the material loss are analyzed in the bottom graph for various bending radiuses in 90° turn (arc S=R·θ).
The loss due to sidewalls surface roughness (A, Lc) was included in the simulation.
