- Abstract
- We studied the influence of nanorod (NR) morphology on the optical confinement. In order to understand the optical field confinement by the ZnO NR, we obtained the spatial intensity distribution inside/outside the NR by solving Maxwell equations using the finite-difference time-domain numerical simulation. The hexagonal cylinder-shaped NR exhibits a strong confinement and the circular cylinder-shaped NR shows also similar confinement effect. Meanwhile, the rectangular cylinder-shaped NR, the tapered NR, and the NR with sharp cone show a weak confinement of optical field as compared to that of the hexagonal cylinder-shaped NR. Next, as the rod length and/or the rod diameter increase, the high intensity region increases. This suggests that longer nanorod will exhibit more efficient lasing action.
