BlochMode

Mode inside a BlochStack.

Member functions:

• kz(): returns propagation factor.
• n_eff(): returns effective index.
• pol(): returns polarisation.
• field(Coord): returns field at a given coordinate.
• fw_field(): returns expansion coefficients of forward field component of this mode.
• bw_field(): returns expansion coefficients of backward field component of this mode.
• fw_bw(z, limit=Min): returns a tuple with two vectors containing the forward and backward field expansions at position z. limit is optional and can be either Min or Plus.
• S_flux(Complex x0, Complex x1, Real eps): returns power flux in the z-direction at z=0 between x0 and x1, calculated with relative precision eps.
• plot_field(): lower level field plot routine. See Stack for more details.
• animate_field(): lower level field plot routine. See Stack for more details.
