Abstract

En akustooptisk bølgelederanordning for bølgelengdeutvelgelse omfattende et substrat (30) av et dobbeltbrytende og fotoelastisk materiale på hvilket det er dannet et første og et andre rota-sjonstrinn av polarisasjonsplanet til et optisk signal i et første bølgelengde-intervall. Hvert trinn omfatter minst én optisk bølgeleder (35, 36) som gjennom-løpes av signalet, minst én optisk bøl-geleder som forbinder de to trinn og bærer en eneste polarisator bestående av en svinnblge-polarisasjonskopler (40), og minst én optisk bølgeleder som bærer én polarisator (37) og er anordnet ned-strøms av det andre trinn.
