Introduction,st ever since the early 1960’s, when the development of the laser first provided a stable source of coherent light for such applications. Laser beams can be transmitted through the air, but atmospheric variations cause undesirable changes in the optical characteristics of the path from day to day, a

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. In this ch

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

The device is considered to be a modulator if its primary function is to impress information on a light wave by temporaly var
