Dispersion is the spreading of light pulse as its travels down the length of an optical fiber. Dispersion limits the bandwidth or information carrying capacity of a fiber. Index Terms- Optical Fibers, Dispersions, Modal Dispersions,. Material Dispersion, Wave Guide Dispersions, Polarization. Dispersions, Chromatic Dispersions.

Faci l ity, for intermodal dispersion measurements is discussed in detail, together with the procedure for its short optical pulses, pulse dispersion in an optical fibre,and hence its bandwidth, can be di rectl y and . wavelength, of the relatlve refractive-index difference between core and cladding. T will be important only in
note that this two terms are related to light propagation through fiber optics hence i will have to answer in a optical fiber communication point of view. What is a gamma point in a dispersion w(k) diagram? How does the light disperse when it passes through a prism?
Intramodal dispersion: Pulse broadening within a single mode is called as intramodal dispersion or chromatic dispersion. The two main causes of intramodal dispersion are as follows: a. Material dispersion: • It is the pulse spreading due to the dispersive properties of material. • It arises from variation of
UNIT I 1. Explain the intermodal and intramodal dispersion. What are draw back of dispersion .and how can we minimize dispersion? Compare dispersion shifted and dispersion flattened fiber. 2. Explain the following terms related to optical laws:(a) Snell's Law (b) Critical Angle (c) Total Internal Reflection (d) Refractive
Material Dispersion. Waveguide Dispersion. b-V Diagram. Inter-Modal Dispersion. Polarization Mode Dispersion (PMD). Dispersion is a phenomenon related to the variation in velocity of different frequencies. (wavelengths) or (1) Intra-modal or Chromatic dispersion (present in single mode an multimode optical fiber).
Dispersion: Dispersion is the broadening of actual time-width of the pulse due to material properties and imperfections. As pulse travels down the fiber, dispersion causes pulse spreading. This limits the distance travelled by the pulse and the bit rate of data on optical fiber. In a fiber three distinct types of
Sep 29, 2011 Inter-modal dispersion: The term “Inter-modal" consists of two terms “inter" and “modal". “inter" Therefore, intermodal dispersion means the dispersion between the different modes of the fiber. “intra" means “within same" and “modal" term comes from mode (mode means path followed by the light).
a. Outline the differences between inter and intra-modal dispersion. [3] b. Show that for a step index multimode fibre of length L, and average core/cladding refractive indexes nav, the pulse widening, ?t, due to inter-modal dispersion is given by: ?t ? [L/(2cnav)] x NA2.
