- Abstract
A description of developing a photonic crystal nanocavity is presented. The designing of a nanocavity on a Nb2O5 substrate was analysed by the finite difference time-domain (FDTD) method to find the resonant frequency, quality factor and mode profile of the cavity mode. The result showed that the resonant frequencies are 179 and 193 THz and by photoluminescence 190 to 250 THz. By optimizing the inner radius of the hole defects to achieve the best quality factor, the diameter was 0.170 μm and that of outside holes was 0.194 μm.
