Waveguide (optics) For waveguides for electromagnetic wave propagation at microwave and radio wave frequencies, see Waveguide (electromagnetism). For other types of waveguide, see Waveguide. 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. Optical waveguides are used as components in integrated optical circuits or as the transmission medium in local and long haul optical communication systems.

Waveguide Dispersion Waveguide dispersion is important in waveguides with small effective mode areas. Examples are optical fibers, in particular certain photonic crystal fibers, but also other single-mode fibers as used in, e.g., optical fiber communications.aveguide dispersion is chromatic dispersion which arises from waveguide effects: the dispersive phase shifts for a wave in a waveguide differ from those which the wave would experience in a homogeneous medium. The total dispersion is the combination of material dispersion and waveguide dispersion.

Ultra-compact head-up displays based on freeform waveguide [0002] It is highly desirable in developing a head-up display (HUD) with a waveguide-like ultra-compact form factor to maintain a large field of view (FOV), a large, uniform eye box, a long eye relief, and high image brightness. Such a display has a wide range of applications in aviation, automobile, and military fields.

What is a cross-guide coupler? Credit: Thomas Barwick Stone Getty Images. A cross-guide coupler is a kind of waveguide. Waveguides are hollow metal cylinders or boxes that transmit electrical current. They are only useful for transmitting electricity if the electrical signal has a very high frequency, which is the case with microwave energy.

What Is a Mica Waveguide Cover for a Microwave? Microwave ovens are relatively simple electronic cooking appliances. The cooking chamber has a hole for the passage of microwaves, generated by a specialized vacuum tube. The mica waveguide cover is a selective filter that covers the hole in the cooking chamber. It allows microwaves to reach the food, while preventing food particles and moisture from entering the electronic components of the oven. A hole in the waveguide cover can cause a fire in the cooking chamber of the microwave.
