Skewness

Skewness

The measures of central tendency calculated from a data set may not reveal much about its intrinsic distribution. If a plot is made of the data set’s values, the mean and the median may not only differ, but also the plot may have more values on one side of the central tendencies. Such a data set is said to be skewed towards that side.
The longer the tail of the plot on one side, the more skewed it is. The skewness of a data set’s values suggests that the measures of central tendency are...

Types of Skewness

Types of Skewness

If the frequency distribution of a data set is more inclined towards smaller or larger values, the distribution is said to be skewed. If data values are skewed to the right, then the distribution is called positively skewed. Conversely, if the plot is skewed to the left, the distribution is called negatively skewed.
For instance, in the middle of a pandemic, the geographical distribution of vaccine coverage may be positively skewed towards populations in the global north countries. However,...

Focusing of Light in the Eye

Focusing of Light in the Eye

Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Energy Stored In A Coaxial Cable

Energy Stored In A Coaxial Cable

A coaxial cable consists of a central copper conductor used for transmitting signals, followed by an insulator shield, a metallic braided mesh that prevents signal interference, and a plastic layer that encases the entire assembly.
In the simplest form, a coaxial cable can be represented by two long hollow concentric cylinders in which the current flows in opposite directions. The magnetic field inside and outside the coaxial cable is determined by using Ampère's law. The magnetic field inside...

Skew rays in optical fibers.

A Cozannet, M Treheux

|February 16, 2010

Summary

This study analyzes optical fiber behavior using the Eikonal equation. Skew rays can cause delays in impulse responses but are often negligible for solid-state laser sources.

Area of Science:

Optics and Photonics
Fiber Optics Communications

Background:

Meridional analysis is a common method for studying light propagation in optical fibers.
Understanding the behavior of skew rays is crucial for accurate fiber optic modeling.

Purpose of the Study:

To justify the use of meridional analysis by examining the impact of skew rays.
To analyze the Eikonal equation without approximation for different index profiles.

Main Methods:

Solving the Eikonal equation without approximation for two index profile cases.
Investigating limit conditions for skew rays.
Analyzing impulse response characteristics.

Main Results:

Skew rays, with inclination exceeding the meridional critical angle, introduce a delay (queue) in the fiber's impulse response.

For solid-state laser sources, the energy carried by skew rays is insignificant.

Conclusions:

Skew rays can be neglected in the analysis of impulse response for solid-state laser sources.
Meridional analysis is validated under specific conditions due to the negligible impact of skew rays.
