Paper Abstract

As the equivalent refractive index solution and the Fraunhofer approximation of scalar diffraction integral formula are engaged, the far field diffraction characteristics of TE0 mode symmetrical multiple quantum well planar waveguide is discussed. Based on the Fourier transform relation between the near field distribution and far field diffraction distribution, the relation among the near field half width, far field divergence half angle and beam propagation factor for non-paraxial light beam are analysed and some approximate relationship with definite physical meaning are presented. Then, the approximate characteristics of beam propagation factor, near field half width defined by equivalent matching efficiency and tangent value of far field divergence half angle defined by equivalent matching efficiency versus the number of potential well layers of TE0 mode symmetrical MQW planar waveguide are presented.
