What is waveguide in optical Fibre?

What is waveguide in optical Fibre?

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).

Is Fiber Optic a waveguide?

Optical fiber is actually a waveguide for light and operates in accordance with a principle known as total internal reflection. Total internal reflection happens when a propagated wave strikes the boundary between two dissimilar materials, provided that the angle of incidence is larger than the critical angle.

Which waveguide is widely used in optical fiber?

Circular waveguides, commonly referred to as optical fibers, are the most common form of light waveguide used for optical communication.

Which theory is used in optical 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 that are used most often in optical integrated circuits, the planar waveguide and the rectangular waveguide.

What are the two types of optical waveguides by mode structure?

There are two main types of optical waveguide structures: the step index and the graded index.

What is a waveguide mode?

Waveguide mode stands for a unique distribution of transverse and longitudinal components of the electric and magnetic fields. There are two types of waveguide modes that can propagate in the waveguides: TE (Transverse Electric) and TM (Transverse Magnetic).

What is passive waveguide?

Passive waveguide device technologies — Building block of functionality and integration. Abstract: Any function can be realized by passive waveguide devices, without emission and detection. Integration is a natural consequence of the requirements of functionality, less connection points, compactness and stabilization.

What is quasi TEM mode?

Quasi TEM wave mode exist in a microstrip line. The term quasi refers that this wave is resembling to TEM wave. As we know in microstrip top and bottom is conductor part and middle one is dielectric. Hence in microstrip, wave propagates through the air above the top pattern and through the dielectric substrate.

What are the principles of optical networks?

Principle and advantages of optical communication

  • Long transmission distance, economical and energy saving.
  • Transfer huge amount of information at one time.
  • Communication speed is fast.

What are the different types of waveguides in optics?

Waveguide (optics) Optical waveguides can be classified according to their geometry (planar, strip, or fiber waveguides), mode structure ( single-mode, multi-mode ), refractive index distribution (step or gradient index) and material ( glass, polymer, semiconductor ).

How are waveguides used in optical fiber fabrication?

Usually, a waveguide contains a region of increased refractive index, compared with the surrounding medium (called cladding ). However, guidance is also possible, e.g., by the use of reflections, e.g. at metallic interfaces. Some waveguides also involve plasmonic effects at metals.

How are waveguides used in digital processor chips?

In the future, silicon waveguides on digital processor chips and polymer waveguides in circuit boards may be used for fast optical data transmission between components of computers. Some waveguides are used for maintaining high optical intensities over appreciable lengths, e.g. in nonlinear devices such as frequency doublers and Raman lasers .
