Abstract
We consider a propagation of ultrashort optical pulses, which can be represented as discrete solitons in bilayer graphene waveguides. The effective equation, in the form of the classical sine-Gordon equation analog, was obtained. The effects associated with change in width of initial momentum and of the Coulomb energy were investigated.
