ABSTRACT:
The Q factor and electric field pattern (radiation pattern) for a cavity made from a donor-type point defect4as is illustrated in FIG.1were simulated by the FDTD method. The simulation parameters were configured by selecting silicon for the slab1; and setting approximately 1.55 μm, which is generally used in optical communications, for the wavelength λ; 0.42 μm for the lattice constant a; 0.6a for the slab1thickness; and 0.29a for the predetermined sectional radius of the through-holes2.
