Abstract: Traditionally, the single-barrier photonic quantum tunneling has been studied via a formal analogy between the Helmholtz equation of electromagnetic waves in a waveguide or total internal reflection and the stationary Schrdinger equation of a massive particle in a single barrier, from which the tunneling probability of photons is directly obtained without taking into account the physics of the electromagnetic field itself, such that it is neither strict nor complete. More importantly, so far, the quantum resonance tunneling effect of photons passing through a multi-barrier has not been systematically studied. In this paper, starting from the physics of the electromagnetic field itself, a strictly theoretical model for photonic quantum tunneling through a single barrier is established, and some new results are obtained. Further, the quantum tunneling of guided photons through a multibarrier is studied, where the analytical expression of photonic tunneling probability is obtained, based on which the quantum resonance tunneling effect of photons and its physical characteristics are studied. A preliminary study of controlling light with light based on the photonic resonanct tunneling is presented.
