摘要
从矩形空气孔光子晶体平板的研究入手，设计了一种新型的正方形空气孔L3型光子晶体平板微腔。采用有限时域差分法，计算了正方形空气孔L3型光子晶体微腔的Q值、模体积及谐振频率；讨论了正方形空气孔边长对微腔Q值、模体积及谐振频率的影响。对L3型光子晶体平板微腔进行了优化，设计出了Q值为27719、模体积为0.4361(λ/n)3、谐振波长为1543 nm的正方形空气孔的L3型光子晶体平板微腔。该L3型光子晶体平板微腔的Purcell因子高达4767。
Abstract
According to the research of rectangular photonic crystal slab, an L3 square air holes photonic crystal cavity is proposed. The Q factors, mode volumes, and resonant frequencies of L3 square air holes photonic crystal cavities with different side lengths are discussed using finite difference time domain (FDTD) method. Based on the results, an L3 square air holes photonic crystal cavity is proposed and a fairly high Q value of 27719 is obtained, with the mode volume of 0.4361(λ/n)3 and the resonant wavelength at 1543 nm. The Purcell factor of the L3 square air holes photonic crystal cavity is as high as 4767.
