Abstract:
(EN) Disclosed are a variable wavelength filter, and a light receiver and light receiving method using the variable wavelength filter. An aspect of the present embodiment provides a light receiving module including a variable wavelength filter which allows light transmitted therethrough or reflected thereby to have a variable wavelength, the light receiving module comprising: a variable wavelength filter which allows only light having a pre-configured wavelength to transmit therethrough and can selectively change the pre-configured wavelength; a heat generating unit which is in contact with at least one surface of the variable wavelength filter; and a separating unit which has a pre-configured heat transfer rate, is in contact with at least a part of the variable wavelength filter to support the variable wavelength filter, and physically or thermally separates the variable wavelength filter from the other components in the light receiving module except for the heat generating unit, wherein the pre-configured wavelength is determined by a temperature of the heat generating unit.
(FR) L'invention concerne un filtre à longueur d'onde variable, ainsi qu'un récepteur de lumière et un procédé de réception de lumière utilisant le filtre à longueur d'onde variable. Un aspect du présent mode de réalisation concerne un module de réception de lumière comprenant un filtre à longueur d'onde variable qui permet à une lumière transmise ou réfléchie par l'intermédiaire de celui-ci d'avoir une longueur d'onde variable. Le module de réception de lumière comprend : un filtre à longueur d'onde variable qui permet uniquement la transmission d'une lumière ayant une longueur d'onde prédéfinie par l'intermédiaire de celui-ci et qui peut modifier sélectivement la longueur d'onde prédéfinie; une unité de génération de chaleur qui est en contact avec au moins une surface du filtre à longueur d'onde variable; et une unité de séparation qui a un taux de transfert de chaleur prédéfini, qui est en contact avec au moins une partie du filtre à longueur d'onde variable de façon à le supporter et qui sépare physiquement ou thermiquement le filtre à longueur d'onde variable des autres composants dans le module de réception de lumière, à l'exception de l'unité de génération de chaleur. La longueur d'onde prédéfinie est déterminée par une température de l'unité de génération de chaleur.
