It calculates the cutoff wavelength and single-mode bandwidth at the change of the ridge dimensions, gives the dominant mode field pattern and the corresponding curve of the deformation vs.
The paper computes the cutoff wavelength and field pattern at different ridge positions in asymmetric single ridge waveguide and L-shape waveguide. Some computational data and figures are presented.
