Optical Waveguide Modes,s in an electrical integrated circuit. However, unlike electrical current that flows through a metal strip according to Ohm’s law, optical waves travel in the waveguide in distinct optical modes. A mode, in this sense, is a spatial distribution of optical energy in one or more dimensions that remain

Waveguide Fabrication Techniques,ce in the index of refraction between the waveguiding region and the surrounding media. A great many techniques have been devised for producing that required index difference. Each method has particular advantages and disadvantages, and no single method can be said to be clearly superior. The choice

Losses in Optical Waveguides, as to which modes propagate, the next most important characteristic of a waveguide is the attenuation, or loss, that a light wave experiences as it travels through the guide. This loss is generally attributable to three different mechanisms: scattering, absorption and radiation. Scattering loss usu

Waveguide Input and Output Couplers,e detail the various coupling techniques that can be used. The methods that are employed for coupling an optical beam between two waveguides are different from those used for coupling an optical beam in free space to a waveguide. Also, some couplers selectively couple energy to a given waveguide mod

Coupling Between Waveguides,couple one wave-guide to another. Couplers of this type are usually called directional couplers because the energy is transferred in a coherent fashion so that the direction of propagation is maintained. Directional couplers have been fabricated in two basic geometries: multilayer planar structures,
