Introduction. This module simulates the transverse electric (TE) guided modes of a planar dielectric waveguide for light of a fixed angular frequency, w. The module displays the wave function of the electric field of the mode, and it allows the user to vary the relevant parameters and to animate the Outline. 1 Revision: waves in optics. 2 Waveguide modes.

Optical waveguides can be classified according to their geometry (planar, strip, or fiber waveguides), mode structure (single-mode, multi-mode), refractive index In general many modes. are excited in the guide. resulting in complicated. field and intensity. patterns that evolve in a. complex way as the light. propagates down the guide. Fundamentals of Photonics - Saleh and Teich. Planar Mirror Waveguide. The planar mirror waveguide can be. solved by starting with Maxwells For each value of V : -determine the number of existing symmetrical and antisymmetrical modes.

Sep 29, 2014 Modes in planar waveguide The optical wave is effectively confined within the guide and the electric field distribution in the x direction does not change as the wave propagates in z direction. The stable field distribution in the x direction with only aperiodic z dependence is known as a mode. A specific waveguides, mode structure: single-mode, multi-mode, refractive index distribution: step or gradient index and material: glass, polymer, semiconductor. Here we discuss the planar dielectric waveguide specifically from the configuration, waveguide mode, field distribution, dispersion relation and group velocity aspects. We will now show how optical tunnelling can be exploited for the excitation of the guided modes of a planar waveguide. 7.4 THE PRISM COUPLER. Planar guided modes can be excited by an external free-space beam using a prism coupler, shown in Figure 7.4-1. This consists of a prism of suitable refractive index, which is. of waveguide theory are presented with minimal proof to give the reader a general understanding of the nature of light propagation in an optical waveguide. Then, in. Chap. 3, a mathematically sound development of waveguide theory is given. 2.1 Modes in a Planar Waveguide Structure. As shown in Fig. 2.1, a planar$
