Abstract

This letter presents the theoretical investigation model to calculate the defect modes, modes loss of the slab, the group velocity of the defect region, and then calculate the normalized frequency of the defect region of Al_xGa_1-xAs at a wavelength of 1550 nm. A fast Fourier transform method was used to find the effect of varying refractive index on the modes frequency. This change of the refractive index enhancement is attributed to the transmission.
