Investigation on effect of air-holes taper in a photonic crystal nanobeam cavity structure on the quality factor, using COMSOL Multiphysics
Abstract:   (4171 Views)
In this paper, confined modes in the photonic crystal nanobeam cavities containing air-holes taper is investigated which support small mode volume and high quality factor (Q). Computational results on this type of photonic crystal nanobeam structure demonstrate further increasing of the Q-value approximately 20550 in the fiber optics telecommunications wavelength range. The maximum Q-values obtained by combination of both nanocavity’s neighboring tapers and ends tapers plus carefully designed air-hole diameters and their non-periodic displacements within the tapered sections. Simulation in this paper is done using COMSOL Multiphysics software based upon the finite element method in the frequency domain.
