Abstract

Eine Mehrzahl von Michelson-Interferometer-Stufen, die jeweils mit einem optischen Richtungskoppler und zwei gechirpten Bragg-Gittern als das über den Eingangs-Lichtwellenleiter eintretende Licht vollständig zum Ausgangs-Lichtwellenleiter reflektierenden Reflektoren gebildet sind, ist zu einer Kaskade zusammengeschaltet, in der jeweils der Ausgangs-Lichtwellenleiter des Interferometers einer Stufe in den Eingangs-Lichtwellenleiter des Interferometers der jeweils nachfolgenden Stufe übergeht. In dieser Schaltungsanordnung, die als IO-(Integrierte-Optik-)Schaltung ausgebildet sein kann, ist eine Mehrzahl von Michelson-Interferometer-Stufern (I1, I2, I3, ..., IN) vorgesehen, die jeweils mit einem optischen Richtungskoppler (RK) und zwei geschirpten Bragg-Gittern (G) gebildet sind, von denen her das über den jeweiligen Eingangs-Lichtwellenleiter (E, E2, E3, ..., EN) eintretende Licht vollständig zum jeweiligen Ausgang-Lichtwellenleiter (A1, A2, A3, ..., A) reflektiert wird. Zu einer solchen vollständigen Reflexion des eingetretenen Lichts zum Ausgang hin kommt es, bei entsprechender Phasenlage der Beiden von den beiden Bragg-Gitter (G) reflektierten Lichtstrahlen, wobei eine solche Phasenlage durch einen Phasenabgleich in dem Phasenabgleichbereich (Ph) zwischen dem Strahlteiler (RK) und dem einen Bragg-Gitter herbeigeführt wird.
