Beschreibung
Zusammenfassung:	A tunable optical signal device and method of using the same having at least two filter elements, each of said filter elements being made of a material having an adjustable parameter, wherein the adjustable parameter is maintained at slightly different values for adjacent filter elements. La présente invention concerne un dispositif de signal optique accordable, et son procédé d'utilisation, comprenant au moins deux éléments filtrants. Chacun desdits éléments est constitué par un matériau assorti d'un paramètre réglable, ce paramètre réglable étant maintenu à des valeurs légèrement différentes pour des éléments filtrants adjacents.
