The invention pertains to a method for switching an optical signal from a digital thermo-optical switch input port to at least one output port of the switch, with a temperature difference being imposed between at least two of the output ports, and with said temperature difference at the outset being greater than or equal to .DELTA.Tmin (the minimum difference required for switching) and subsequently being reduced to one of less than .DELTA.Tmin. This switching scheme greatly reduces the thermal load on the digital thermo- optical switch.
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.
