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.
