Abstract

The present paper establishes the photonic superguiding theory in polar crystals with a high nonlinearity. In the quantum theory it is shown that photons can feel an attractive effective interaction by exchanging of virtual phonons. Such an interaction leads to the superguiding state, in which photons with opposite wave vectors and spins are bound into pairs. The photon pairs travel without scattering attenuations. In the classical theory we prove that the crystals exhibiting the photonic superguiding state are the self-defocusing media in which temporal bright solitons can propagate. The optical solitons do not suffer from dispersion. If the photons propagating in a waveguide enter the superguiding state, the waveguide exhibits both an ultralow energy loss and a high transmission rate.
