Abstract
In this paper, we numerically study asymmetric Fano line shape realized in a photonic crystal nanobeam (PCN) side-coupled with a photonic crystal nanobeam cavity (PCNC). The Fano resonances can be controlled by the photonic band gap of the PCN. If changing the symmetry of cavity mode, the Fano line shape can also be changed correspondingly.
