Query: Quantum effect of one-dimensional photonic crystal   In this paper, we have studied the quantum transmission characteristics of
one-dimensional photonic crystal with and without defect layer by the quantum
theory approach, and compared the calculation results of classical with quantum
theory. We have found some new quantum effects in the one-dimensional photonic
crystal. When the incident angle $\theta=0$, there is no quantum effect. When
the incident angle $\theta\neq0$, we find there are obvious quantum effect with
the incident angle increase. At the incident angle $\theta\neq0$, there are
also quantum effect with the change of thickness and refractive indexes of
medium $B$ or $A$. We think the new quantum effect of photonic crystal shall
help us to design optical devices.
