In this paper, the structure being investigated consists of periodic layers of InGaP containing a defect region in air hole and GaAs. Finite difference time-domain calculations were performed to show the influences of hole radius on the group velocity (\( V_{g} \)), quality (\( Q \)) factor and transmission of the structure. As well as effect the hole radius deviation on the \( Q \) factor. Also, we will investigate property of the defect region on the band structures.
