研究了三角形晶格空气孔光子晶体环形谐振腔（PCRR）的线性传输特性，分别采用约化折射率耦合和三波导耦合结构，研究了耦合区域对PCRR线性传输特性的影响。工作在色散曲线线性区的PCR谐振腔模式有利于获得尖锐的谐振，从而建立行波特性，实现单向下降。此外，我们还研究了光学双稳态对初始频率失谐量和输入光强的依赖关系。当失谐量较大时，会发生不稳定振荡。
We have studied the effect of the coupling region on the linear transmission characteristics of two types of photonic crystal ring resonator (PCRR) with a triangular lattice of air holes using reduced refractive-index coupling and three-waveguide coupling structures. The cavity mode in PCRRs working in the linear region of dispersion curves is preferable to obtain sharp resonance, which can establish traveling-wave behavior and realize one-directional dropping. In addition, we investigate the dependence of optical bistability on initial frequency detuning and input intensity. Unstable oscillations take place when detuning is large.
