For increasing the effect of confinement of light in photonic cavity,based on the optimized first round air holes of the H2 photonic cavity,the second round air-holes were optimized,and the Q factor increased by 60%. When adjusting the third and fourth ring air-holes to the ring position,the results show that the effect of confinement of light by round air-holes structure conflicts with that of photonic crystal. The Q factor does not always increase with the rounds increasing by round air-holes structure.
The photonic crystal(PhC) cavities with whispering-gallery mode have got more attention by researchers. For increasing Quality-factor(Q factor), we optimize the second round air-holes of the H2 photonic cavity which has been already optimized the first round air holes. And we get 60% Q factor increasing. By researching the third and fourth round air-holes structures, we find out that the effect of confinement of light by round air-holes structure conflict with the effect by photonic crystal. The Q factor do not always increase with the rounds increasing by round air-holes structure.
