The quantum theory and topological features of photon

In this paper, we have proposed the spinor wave equation of free and non-free photon. On this basis, we given the spin operators and spin wave functions of photon, and calculated the wave function of photon in vacuum and medium. In addition, we have given the quantum Berry phase and Chern number with the photon wave function, which can be used to studied the quantum topological features of photon in one-dimensional period medium.

The design of ultra-strong laser with one-dimensional function photonic crystal

With the optical kerr effect, the conventional photonic crystal can be turned into the function photonic crystal under the action of pump light. In the paper, we have designed the ultra-strong light source and laser with one-dimensional function photonic crystal. When the incident light is the ordinary light, the output is ultra-strong light source, and when the incident light is the low power laser, the output is ultra-strong laser, the maximum magnification can be reached $10^{80}$ and even more. Otherwise, we analyzed the effect of period number, medium refractive index and thickness, incident angle, the pump light irradiation way and pump light intensity on the magnification, these results shall help to optimal design ultra-strong light source and laser.
