An open cavity formed with a photonic crystal of negative refraction
Zhichao Ruan, Sailing He
A novel open cavity formed by three 60-degree wedges of a photonic crystal with negative effective index is designed and studied. The quality factor of the open cavity can be large…
Explicit formula for the external driving field used to eliminate the decoherence of a two-state system coupled to a noise field
Jian-Qi Shen, Zhi-Chao Ruan, Sailing He
The elimination of decoherence of a multiphoton two-state quantum system by using an appropriate external driving field is considered. The multiphoton process caused by the noise f…
Abnormal phenomena in a one-dimensional periodic structure containing left-handed materials
Liang Wu, Sailing He, Linfang Shen
The explicit dispersion equation for a one-dimensional periodic structure with alternative layers of left-handed material (LHM) and right-handed material (RHM) is given and analyze…
Degeneracy analysis for a super cell of a photonic crystal and its application to the creation of band gaps
Liang Wu, Sailing He
A method is introduced to analyze the degeneracy properties of the band structure of a photonic crystal making use of the super cells. The band structure associated with a super ce…
