Title
(EN) A TUNABLE FILTER HAVING DIFFERENT GAPS
(FR) FILTRE ACCORDABLE AYANT DIFFÉRENTS ÉCARTEMENTS
Abstract
(EN)
A tunable filter that may include a pair of optical components, wherein there is an optical gap between the pair of optical components; and a pair of actuating elements that are configured, once supplied with at least one actuating signal, to be positioned at an actuation gap from each other and to define the optical gap; and wherein the optical gap is substantially smaller than the actuation gap.
(FR)
Filtre accordable qui peut comprendre une paire de composants optiques dans lequel il existe un espace optique entre la paire de composants optiques ; et une paire d'éléments d'actionnement configurés, une fois fourni avec au moins un signal d'actionnement, pour être positionné au niveau d'un espace d'actionnement l'un de l'autre et pour définir l'espace optique ; l'espace optique étant sensiblement plus petit que l'espace d'actionnement.
