The polymer optical fibers can have a variety of index refraction profiles, such as step index or GRIN (graded-index) profiles.

The first refractive index contrast is smaller than the second refractive index contrast.

A first of the layers is of uniform refractive index n! surrounding a second of the layers of uniform refractive index n2.

Points on a same refractive index straight line within each refractive rate distribution area have identical refractive indexes.

The invention provides differential refractive index detectors and methods for the use of differential refractive index detectors.

The subject method can allow continuous high-speed production while controlling the refractive index profile, step or graded, of the optical transmission medium.

In addition, the intermediate-refractive-index layers (4) contain the materials of the low-refractive-index layers (2) and the high-refractive-index layers (3).

Each refractive index distribution area forms therein multiple refractive index straight lines parallel to each other.

The refractive index difference between the light-transmitting cover (20) and the refractive index matching layer (28) is smaller than the refractive index difference between the light-transmitting cover (20) and the air.
