Abstract

L'invention concerne des ensembles pratiques et à faible consommation d'énergie (1) destinés à appliquer un gradient de température à un réseau de Bragg sur fibre (5). Une application de ces ensembles consiste, par exemple, en un réglage actif de la dispersion chromatique du réseau. Le gradient de température est produit dans un élément conducteur de chaleur (7), avec lequel le réseau de Bragg sur fibre (5) est en contact thermique continu, à travers des éléments (9, 11) commandant la température des extrémités de l'élément conducteur de chaleur (7), appliquant ainsi le gradient de température au réseau de Bragg sur fibre. Un premier mode de réalisation préféré comprend un élément de recirculation de la chaleur (17) permettant la recirculation de la chaleur entre les deux extrémités (29, 31) de l'élément conducteur de chaleur de forme allongée, fournissant ainsi un réglage rapide et dynamique du gradient de température avec une perte de chaleur minimale. Un second mode de réalisation fournit une isolation de l'environnement extérieur afin de découpler le gradient de température souhaité des fluctuations de température ambiante, améliorant ainsi la commande de la réaction optique d'un réseau de fibres.
