Abstract
An apparatus and method of manufacturing sheets with varying concentrations of particles are described. In one embodiment, a method comprises manufacturing a first sheet having a varying concentration of particles. A second sheet having a second concentration of particles and a first shape with varying thickness is provided. A third sheet having a third concentration of particles and a second shape with varying thickness is provided. The second sheet and the third sheet are merged to generate the first sheet.
Claims17
A method, comprising:
- manufacturing an apparatus comprising a first sheet and a light source disposed near an edge of the first sheet comprising,
- manufacturing a first sheet comprising particles, from a second sheet and a third sheet,
- the concentration of particles in the first sheet being uniform through the entire thickness direction of the first sheet at any location on the first sheet and the concentration of particles continuously varying across the entire width and/or the entire length of the first sheet;
- providing the second sheet having a second concentration of particles and a first shape with varying thickness,
- providing the third sheet having a third concentration of particles and a second shape with varying thickness, and
- merging the second sheet and the third sheet along curved surfaces of the second sheet and the third sheet to generate the first sheet;
- wherein
- the second sheet is merged to the third sheet by fusion, which comprises physical diffusion of the particles from the second sheet into the third sheet;
- the physical diffusion is strong enough to cause a local homogenization of the concentration of the particles of the first sheet without causing the homogenization of the concentration of the particles over the whole of the first sheet;
- and
- the local homogenization comprises homogenization spanning the thickness of the first sheet.

A method, comprising,
- manufacturing a first sheet having a plurality of first columnar bodies, each first columnar body having particles, the concentration of particles in each first columnar body being uniform through the entire thickness direction of that first columnar body at any location on that first columnar body and the concentration of particles continuously varying across the entire length of that first columnar body;
- providing multiple second columnar bodies, each having a particular concentration of particles, and varying thickness,
- providing multiple third columnar bodies, each having a particular concentration of particles, and varying thickness, and
- merging the multiple second columnar bodies and the multiple third columnar bodies to produce the plurality of first columnar bodies;
- wherein
- the multiple second columnar bodies are merged to the multiple third columnar bodies by fusion, which comprises physical diffusion of the particles from the multiple second columnar bodies into the multiple third columnar bodies;
- a columnar body is a body extended primarily in one direction;
- and
- each first columnar body is a waveguide capable of conducting light along its length.
