1. A rod comprising:
- an optically transmissive body having a length and a cross-section transverse to the length with a maximum dimension along the cross-section that is from 500 μ
m to up to 10 cm, the optically transmissive body having air-filled lines, voids, or gas-filled lines or voids distributed in a disordered manner over at least a central portion of the cross-sectional area of the body and collectively extending along the entire length of the body, whereby light launched into the body within id central portion of the body is confined in a direction transverse to the length of the body and is propagated along the length of the body.

Abstract
A rod comprises an optically transmissive body having a length and a cross-section transverse to the length, with a maximum dimension along the cross-section that is from about 500 um to up to 10 cm, the optically transmissive body having air-filled lines, voids, or gas-filled lines that are distributed in a disordered manner over at least a central portion of the cross-section, desirably over the entire cross-section, whereby light launched into the body is confined in a direction transverse to the length of the body and is propagated along the length of the body.

6. A method of forming a rod comprising an optically transmissive body having a length and a cross-section transverse to the length with a maximum dimension along the cross-section that is from 500 μ
- m to up to 10 cm, the optically transmissive body having air-filled lines, voids, or gas-filled lines or voids distributed in a disordered manner over at least a central portion of the cross-sectional area of the body, the method comprising;
forming a plurality of rods or fibers each having air-filled lines, voids, or gas-filled lines or voids distributed in a disordered manner across its respective cross-sectional area; and fusing the plurality of rods or fibers to form a single optically transmissive body having a cross-section with a maximum dimension along the cross-section that is from 500 μ
m to up to 10 cm.
- m to up to 10 cm, the optically transmissive body having air-filled lines, voids, or gas-filled lines or voids distributed in a disordered manner over at least a central portion of the cross-sectional area of the body, the method comprising;

7. A method of transmitting an image, the method comprising:
-
positioning an optically transmissive body, the body having a length and a cross-section transverse to the length with a maximum dimension along the cross-section that is from 500 μ
m to up to 10 cm, the optically transmissive body having air-filled lines, voids, or gas-filled lines or voids distributed in a disordered manner over at least a central portion of the cross-sectional area of the body and collectively extending along the entire length of the body, the body having first and second ends in the length direction, such that the second end of the body is at a position at which an image is to be received; andproviding an image at the first end of said body.
