2 Jan 2017 optics. This chapter is devoted to the theory of these waveguides. Other The simplest dielectric guide is the planar slab guide shown in. Fig.
We present a new approximate solution of the scalar-wave equation for planar optical waveguides with arbitrary refractive-index profiles. Test calculations are
1 Oct 2017Theoretical fundamentals of optical waveguides. • Planar waveguides; waveguide modes, their properties. Guided and leaky modes. Other types of waveguiding
In a planar waveguide that has optical confinement in only one transverse direction, the core is sandwiched between cladding layers in only one direction, say the x direction, with an index profile n(x).
However, unlike electrical current that flows through a metal strip according to Ohm’s law, optical waves travel in the waveguide in distinct opti- cal modes. 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.
