Patent

CA 2199506

An optical fibre comprises a tubular glass cladding (1) with a central opening (2), filled with a colloidal solution of quantum dots (4) in a support medium (3). The quantum dots may be caused to produce luminescence in response to input optical radiation, for example to produce optical amplification or laser radiation. A waveguide with an active medium comprising colloidal quantum dots is claimed.

Fibre optique comprenant une gaine tubulaire en verre (1) pourvue d'une ouverture centrale (2) remplie d'une solution colloïdale de points quantiques (4) dans un milieu de support (3). On peut déclencher la production d'une luminescence par ces points quantiques en réaction à un rayonnement optique d'entrée, afin, par exemple, d'obtenir une amplification optique ou un rayonnement laser. L'invention concerne également un guide d'ondes comportant un milieu actif comprenant des points quantiques colloïdaux.
