      In Optisystem v.14, Why the transverse fields are generated as double numbers (for some modes) not complex numbers?
      where the transmitted mode is LP mode.

      Modes are solutions of Maxwell’s equations which are separable in the propagation direction, z. They have the form

      E(x, y, z) = F(x, y) exp( -j \beta z)

      where E is any of the field components, electric or magnetic. When this equation is substituted into Maxwell’s equations, the resulting equation for F is an equation with material parameters appearing in the coefficients. If those materials are loss-less, they are represented by real numbers. The solution for those equations are usually real valued functions. That is why the modes of loss-less waveguides are represented as real functions.
