We have investigated the localized design of heterostructure photonic crystal nanocavities in order to make them more suitable for integration. While retaining theoretical quality factors of more than ten million, the total length of the heterostructure nanocavity can be reduced to ~5 mum and the shifted air holes comprising the heterostructure can be restricted to the two rows nearest the nanocavity on each side. Though the area for the heterostructure nanocavity investigated thus far was larger than 10 x 10 microm(2) in the photonic crystal slab, heterostructure nanocavities of this new design have sizes of approximately 3 x 5 microm(2), thus allowing dense integration.
我们研究了异质结构光子晶体纳米腔的局部设计，以使它们更适合集成。在保持理论品质因数超过一千万的同时，异质结构纳米腔的总长度可减小至约5微米，并且构成异质结构的移位气孔可限制在每侧最靠近纳米腔的两行。尽管到目前为止所研究的异质结构纳米腔在光子晶体平板中的面积大于10×10微米²，但这种新设计的异质结构纳米腔尺寸约为3×5微米²，从而实现密集集成。
