As defined the example model for pulse propagation will work in normalised units. I strongly recommend reading the example alongside the cited section of Agrawal's "Nonlinear Fiber Optics".

Mohsin. "..is there anything for birefringence or polarization in this toolbox?". No, not explicitly.

"can we simulate pulse propagation in a birefringent fiber by this toolbox?"

Like many things the answer is "it depends".

As long as you can approximate whatever it is that you want to do as being scalar then the answer is "yes" -- just use an effective refractive index for each (decomposed) polarisation. And model it as two separate (decoupled) problems.

If on the other hand the important effect that you want to capture is due to off-diagonal terms in the nonlinear permettivity tensor that strongly couple between polarisation states then the answer is a resounding "No!"; it's tough enough generalising to an N dimensional scalar nonlinear problems, let alone vectorial / tensorial ones!
