Theory of Optical Waveguides,comparison has been made between the physical-optic approach and the ray-optic approach is describing light propagation in a waveguide. In this chapter, the electromagnetic wave theory of the physical-optic approach is developed in detail. Emphasis is placed on the two basic waveguide geometries tha作者: 我悲傷 時間: 2025-3-22 07:04

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作者: 有花 時間: 2025-3-22 16:23
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作者: OVERT 時間: 2025-3-22 18:08
Coupling Between Waveguides,couple one waveguide 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, 作者: palliative-care 時間: 2025-3-22 23:22

Acousto-Optic Modulators,In the preceding chapter, we have shown that modulators and switches can be made by using the electro-optic effect to produce a grating-shaped variation of the index of refraction within the waveguide. This grating structure causes diffraction of the guided optical waves, resulting in modulation or switching.作者: NEX 時間: 2025-3-27 19:35
