Petr Kuzel. Types of guiding structures: • Planar waveguides (integrated optics). • Fibers (communications). Theory: • Rays and field approach. • Various shapes and index profiles. Attenuation and dispersion. Coupling of light into the waveguide An optical wave guide is a structure that "guides" a light wave by constraining it to travel along a certain desired path. If the transverse dimensions of the guide are much larger than the wavelength of the guided light, then we can explain how the optical waveguide works using geometrical optics and total internal reflection Abstract. A simple method is presented for finding the modes on those optical waveguides with a cladding refractive index that differs only slightly from the refractive index of the core. The method applies to waveguides of arbitrary refractive index profile, arbitrary number of propagating modes, and arbitrary cross section. Optical waveguides confine light inside them. • Two types of waveguides exist: ? Metallic waveguides (coaxial cables, useful for microwaves). ? Dielectric waveguides (optical fibers). • This course focuses on dielectric waveguides and optoelectronic devices made with them. • Physical Mechanism: Total Internal Reflection. Inverse scattering theory applied to the design of single-mode planar optical waveguides. A. K. Jordan and S. Lakshmanasamy J. Opt. Soc. Am. A 6(8) 1206-1212 (1989). Transmission characteristics related to Laplacian mode-field half-width of noncircular single-mode waveguides. A. H. Liang Appl. Opt. 36(16) 3793-3801 An optical waveguide is a physical structure that guides electromagnetic waves in the optical spectrum. Common types of optical waveguides include optical fiber and rectangular waveguides. An optical waveguide is a spatially inhomogeneous structure for guiding light, i.e. for restricting the spatial region in which light can propagate. Usually, a waveguide contains a region of increased refractive index, compared with the surrounding medium (called cladding). Optical waveguides are the key elements of photonic devices that perform guiding, coupling, switching, splitting, multiplexing and demultiplexing of optical signals.
