Notes:
The mode frequency and the quality factor of nanowire cavities are calculated from theintensity spectrum obtained by the finite-difference time-domain (FDTD) technique and the Padéapproximation. In the free-standing nanowire cavity with the dielectric constant 6.0 and the lengthof 5 μm, the quality factors of 130, 159, and 151 are obtained for HE11 with frequency around 798THz, at the cavity radius of 60nm, 75nm, and 90nm, respectively. The Q-factor of 78 is alsocalculated in the nanowire with length of 5 μm and radius of 60nm grown on the sapphire substratewith refractive index 1.8. The obtained mode field distribution of the fundamental transverse modeshows that the mode field confined very well by the nanowire cavity even when the radius ofnanowire is much smaller than the mode wavelength
