Abstract

L'invention concerne un procédé pour commuter un signal optique à partir d'un port d'entrée de commutateur thermo-optique numérique vers au moins un port de sortie du commutateur. Une différence de température est alors imposée entre au moins deux ports de sortie. Cette différence est initialement supérieure ou égale à .DELTA.T¿min? (différence minimale requise pour la commutation) et ultérieurement réduite à une valeur inférieure à .DELTA.T¿min?. Ce schéma de commutation permet de réduire significativement la charge thermique sur le commutateur thermo-optique numérique.
