Abstract
The transfer matrix method is employed to analyze the modal propagation within planar InP/InGaAsP antiresonant reflecting optical waveguides (ARROW) at the operational wavelength of 1.55 mu m. The numerical results provide an accurate picture of dispersion and attenuation of both TE and TM polarized waves. Spatial properties of the modes are also investigated and detailed plots of the variation of electric field amplitude with layer thickness are given.
