Theoretical designs for novel photonic crystal nanocavities with Si (111) interfaces
Theoretical designs for novel photonic crystal nanocavities with Si (111) interfaces
We designed a series of Photonic Crystal (PhC) nano-cavities using atomically flat silicon (111) interfaces and examined the impacts of the surfaces on the optical confinement. The nanocavities were simulated using the 3D finite-difference time-domain method and assessed against existing PhCs. Despite the design restrictions, we showed that a Q value up to 115,800 and Q/V values of 10^(3)-10^(5) λ^(-3) are achievable without further design optimisation. The results suggest that silicon (111) surfaces can be used for fabricating PhC nanocavity-based devices in a practical and economical way with high manufacturing tolerance and increased repeatability.

Abstract
We designed a series of Photonic Crystal (PhC) nano-cavities using atomically flat silicon (111) interfaces and examined the impacts of the surfaces on the optical confinement. The nanocavities were simulated using the 3D finite-difference time-domain method and assessed against existing PhCs. Despite the design restrictions, we showed that a Q value up to 115,800 and Q/V values of 10^(3)-10^(5) λ^(-3) are achievable without further design optimisation. The results suggest that silicon (111) surfaces can be used for fabricating PhC nanocavity-based devices in a practical and economical way with high manufacturing tolerance and increased repeatability.
