利用含时波包动力学方法研究了波包在蜂窝状光子晶格中的传播。研究发现，在两个不等价的Dirac点附近，正负能量模叠加后的波包可以转变为双环结构，这是由于Dirac点附近正负能量模的干涉引起的，与Zitterbewegung（ZB）密切相关.同时，提出了一种在蜂窝光子晶格中检测ZB效应的可能方法。
The propagation of a wave packet in a honeycomb photonic lattice has been studied using the time-dependent wave packet dynamics. It is found that the wave packet, superposed from the positive and negative energy modes at the vicinity of the two inequivalent Dirac points, can transform into a double-ring structure, which is caused by the interference between the two positive and negative energy modes around the Dirac points and is closely related to the Zitterbewegung (ZB). Also, a possible way to detect the ZB effect is proposed in the honeycomb photonic lattice.
