摘要
Micro-cavities in two-dimensional silicon-on-insulator (SOI) photonic-crystal slabs are studied. A combination of the finite-difference time-domain (FDTD) technique and the Pad approximation with Baker's algorithm is used to accurately compute the resonant-frequencies and quality,factors simultaneously. The simulations show that, for similar cavity structures, the mode quality factors of cavities in SOI-type photonic-crystal slabs are much smaller than those in membrane photonic-crystal slabs, and deep etching of air holes is still required to obtain relatively higher Omega.
