Abstract

Official abstract text for this publication.

An optical fiber includes: a core including a photosensitive material disposed therein, the core having a first index of refraction; a depressed cladding surrounding the core and having a second index of refraction that is lower than the first index of refraction; and an outer cladding surrounding the depressed cladding and having a third index of refraction that is higher than the depressed cladding.

First claim

Opening claim text (preview).

The invention claimed is: 1. An optical fiber comprising: a core including a refractive index-raising photosensitive material disposed therein, the core having a first index of refraction, the core having a concentration of the photosensitive material, the concentration of the photosensitive material being substantially equal to the lowest concentration that allows fabrication of the fiber Bragg gratings by illuminating the photosensitive material with electromagnetic radiation;…
