The aim of this work is to solve the dispersion relations near the first excitation threshold of a photon propagating along a magnetic field in the strong field limit. We have calculated the time damping of the photon in two particular cases: the degenerate gas as well as the diluted gas limit, both being important from the astro‐physical point of view. In particular, the diluted gas limit could describe the magnetosphere of neutron stars. The solutions have been used to obtain a finite quantum Faraday angle in both limits. A resonant behavior for the Faraday angle is also obtained. To reproduce the semi‐classical result for the Faraday rotation angle, the weak field limit is considered.
