Optimizing Refractive Index for Bright and Even Side Glow in Solid Core Object

In summary, the conversation is about creating a cylindrical object with a black rubber core and transparent or translucent plastic layers to make it glow when light is shone into the side. The question is about the refractive index needed for the outer layer(s) to achieve a bright and even glow, even when the object is bent.

Hi All,

I'm trying to create something which has a solid, cylindrical, non-reflective core (assume the core is made out of a black rubber similar to that of a car tyre for instance and 20m in length, but only 1cm in diameter), which has a translucent or transparent plastic layer (or several layers) wrapped (read: extruded) around this black, solid cylinder.

The purpose of the additional transparent or translucent layers is to ensure when a light is shone into the side of the previously black object, the whole object will glow. Similar to 'side glow optical fibre'.

The question is; what refractive index (or indices) do I need to aim for in the outer layer(s) to ensure the light glows brightly and spreads as evenly as possible along the length of the object longitudinally, even when the object is bent.

Thanks in advance.

Andrew

Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
 

1. What is refractive index?

Refractive index is a measure of how much a material bends light as it passes through it. It is defined as the ratio of the speed of light in a vacuum to the speed of light in the material.

2. How is refractive index measured?

Refractive index is typically measured using a refractometer, which calculates the angle at which a beam of light is bent as it passes through a material. This angle is then used to calculate the refractive index of the material.

3. What is a solid core?

A solid core refers to the innermost layer of a fiber optic cable, which is typically made of a solid material such as glass or plastic. The core is responsible for carrying the light signal through the cable.

4. How does refractive index affect light in a solid core?

The refractive index of the solid core determines how much the light signal will bend as it travels through the core. A higher refractive index means that the light will be bent more, allowing for greater transmission of the signal through the fiber optic cable.

5. Why is refractive index important in fiber optics?

Refractive index is crucial in fiber optics because it determines the efficiency and quality of signal transmission through the fiber optic cable. A higher refractive index allows for better transmission and fewer signal losses, resulting in faster and more reliable communication.
