Abstract
The present invention concerns an optical guide (100) comprising an amplifier medium including: a core (10) in a main matrix of a transparent material, the main matrix containing particules (1, 2), each particule being formed of a submicronic matrix distinct from the main matrix and doped by an active metal element, an external guiding cladding (11) in contact with the core (10). The size of the particules (1, 2) is smaller than 20 nm. The present invention also concerns a method for producing this guide.
Claims22
An optical guide comprising an amplifier medium that comprises:
- a core in a main matrix of a transparent material, the main matrix containing particles, each particle being formed of a submicronic matrix that is distinct from the main matrix and doped by an active metallic element,
- an external guiding cladding in contact with the core,
- wherein the size of the particles is smaller than 20 nm and wherein said active element is not present in the main matrix.
Method for producing an optical guide comprising an amplifier medium including:
- a core in a main matrix of a transparent material, the main matrix containing particles, each formed of a submicronic matrix distinct from the main matrix and doped by an active metallic element,
- an external guiding cladding in contact with the core,
- wherein it includes the following stages:
- a stage for preparing said particles selected from chemical synthesis and laser ablation,
- a stage for incorporating said particles in a precursor of the main matrix.
A method for producing an optical guide comprising an amplifier medium, wherein the amplifier medium comprises a core in a main matrix of a transparent material, the main matrix containing particles that are each formed of a submicronic matrix distinct from the main matrix and doped by an active metallic element, and an external guiding cladding in contact with the core, wherein the method comprises:
- preparing said particles by at least one of chemical synthesis and laser ablation, and incorporating said particles in a precursor of the main matrix.
